We will dissect the problem, break down the calculations, and provide a comprehensive understanding of the underlying principles. This problem not only highlights the fundamentals of probability but also demonstrates how these concepts can be applied to real-world scenarios. Understanding the probability behind such events can give us insights into how systems work and how likely certain outcomes are. This analysis will be crucial for anyone looking to grasp the basics of probability and its practical applications. Let's embark on this mathematical journey to unravel the solution.

Problem Statement

A motorcycle dealership has been assigned a range of license plates for the motorcycles they sell. These license plates must start with the letters "AA" and end with the letter "L". Given this constraint, what is the probability that a customer will be assigned the specific license plate "AAB27L"? This problem combines aspects of combinatorics and probability, requiring us to determine the total number of possible license plates within the given constraints and then calculate the probability of one specific plate being assigned. The challenge lies in understanding how the constraints limit the possible combinations and how to accurately calculate the probability. To solve this, we need to consider the different positions in the license plate and the possible characters that can occupy those positions. This involves a meticulous analysis of the available characters and their placement to arrive at the correct probability. This problem serves as an excellent exercise in applying probability principles to a practical, relatable scenario.

Breaking Down the Problem

To determine the probability of a customer receiving the license plate "AAB27L", we must first calculate the total number of possible license plates that the dealership can issue under the given constraints. The license plates start with "AA" and end with "L", leaving the middle characters to vary. We need to consider the number of positions in the middle and the possible characters for each position. License plates often consist of a combination of letters and numbers, each with its own set of possibilities. Specifically, we need to identify the characters between "AA" and "L" in the license plate format. Typically, these license plates might have a structure like AA[characters]L, where [characters] could be a sequence of letters and/or numbers. The number of characters in this sequence will influence the total number of possible license plates. Understanding this structure is crucial for accurately calculating the total possible license plates. We must consider each position individually and determine the number of possible characters for that position. Once we have the total count, we can then calculate the probability of the specific license plate "AAB27L" being assigned.

Identifying the License Plate Structure

The license plate in question, "AAB27L", provides us with the structure we need to analyze. It consists of six characters: two letters at the beginning ("AA"), three characters in the middle ("B27"), and one letter at the end ("L"). This structure is crucial for calculating the total number of possible license plates. We know the first two positions are fixed as "AA" and the last position is fixed as "L". This leaves us with the three middle positions to consider. Each of these positions can be filled with either a letter or a number, which significantly impacts the total number of combinations. The middle three characters, "B27", are a mix of letters and numbers, giving us a clue about the possible characters that can occupy these positions. We must consider the range of possible letters and numbers that can be used. Understanding the flexibility in these middle positions is key to determining the overall probability. This detailed examination of the license plate structure sets the stage for the next step: calculating the possible combinations for the variable positions.

Determining Possible Characters

Now that we know the structure of the license plate (AA[3 characters]L), we need to determine the possible characters that can fill the three middle positions. Typically, license plates use a combination of letters (A-Z) and numbers (0-9). There are 26 letters in the English alphabet and 10 digits. Thus, each of the three middle positions can be filled with any of these 36 characters (26 letters + 10 numbers). This is a critical piece of information for calculating the total number of possible license plates. Understanding the character set is essential for accurately determining the number of combinations. The assumption that any of the 36 characters can occupy any of the three middle positions simplifies our calculation. However, in some cases, there might be restrictions on which characters can be used in specific positions, which would need to be considered. Given the standard practice of using alphanumeric characters in license plates, our assumption of 36 characters for each position is reasonable. This foundation allows us to move forward with calculating the total number of possible license plates.

Calculating Total Possible License Plates

With the license plate structure defined as AA[3 characters]L and 36 possible characters (26 letters and 10 numbers) for each of the three middle positions, we can now calculate the total number of possible license plates. Each of the three positions can be filled independently, so we multiply the number of possibilities for each position together. This is a fundamental principle of combinatorics, where the total number of outcomes is the product of the number of possibilities for each independent event. To calculate this, we take 36 (possible characters for the first middle position) multiplied by 36 (possible characters for the second middle position) multiplied by 36 (possible characters for the third middle position). This gives us the total number of unique license plate combinations that the dealership can issue within the given constraints. This calculation is the cornerstone of solving our probability problem. Understanding how to combine possibilities in this way is crucial for various probability and combinatorics problems. The result of this calculation will be the denominator in our probability fraction, representing the total possible outcomes.

Mathematical Calculation

To calculate the total number of possible license plates, we perform the following multiplication: 36 * 36 * 36. This can also be expressed as 36³. Calculating this value gives us the total number of unique combinations for the three middle characters of the license plate. 36³ equals 46,656. This means there are 46,656 different possible combinations for the three characters between "AA" and "L". This number represents the total sample space for our probability calculation. The result, 46,656, is a significant number, highlighting the vast number of possible license plates that can be generated under these constraints. This underscores the importance of understanding combinatorics in probability calculations. With this value in hand, we can now proceed to calculate the probability of the specific license plate "AAB27L" being assigned. This calculation brings us closer to answering the original problem statement.

Calculating the Probability

Now that we know the total number of possible license plates is 46,656, we can calculate the probability of a customer being assigned the specific license plate "AAB27L". Probability is defined as the number of favorable outcomes divided by the total number of possible outcomes. In this case, there is only one favorable outcome: the license plate "AAB27L". The total number of possible outcomes is 46,656, as we calculated earlier. To find the probability, we divide the number of favorable outcomes (1) by the total number of possible outcomes (46,656). This will give us the probability as a fraction, which we can then convert to a decimal or percentage if desired. Understanding this fundamental formula for probability is crucial for solving various problems. The simplicity of the calculation belies the depth of the concept it represents. This step is the culmination of our efforts, providing the answer to the question posed at the beginning of this analysis.

Probability Calculation Details

The probability of a customer being assigned the specific license plate "AAB27L" is calculated as follows: Probability = (Number of favorable outcomes) / (Total number of possible outcomes) In our case, this translates to: Probability = 1 / 46,656 This fraction represents the probability of the specific license plate being assigned. To better understand this probability, we can convert it to a decimal. 1 divided by 46,656 is approximately 0.00002143. This is a very small number, indicating that the probability of receiving the specific license plate "AAB27L" is quite low. The decimal form, 0.00002143, provides a tangible sense of how improbable this outcome is. This underscores the power of probability calculations in understanding the likelihood of specific events. Expressing the probability as a fraction or decimal helps contextualize the chances of the event occurring. This final calculation provides the answer to our original problem, illustrating the practical application of probability principles.

In conclusion, the probability of a customer being assigned the specific license plate "AAB27L" at a motorcycle dealership, given that the plates start with "AA" and end with "L", is 1 in 46,656, or approximately 0.00002143. This problem demonstrates the application of basic probability principles and combinatorics in a real-world scenario. By breaking down the problem into smaller parts, such as identifying the license plate structure, determining possible characters, and calculating the total possible license plates, we were able to arrive at the solution. This analysis highlights the importance of understanding the fundamentals of probability and how they can be used to calculate the likelihood of specific events. The problem-solving approach used here can be applied to a variety of similar situations involving probability and combinatorics. Ultimately, understanding probability allows us to make informed decisions and predictions in various aspects of life.
