Buick automobiles come in 4 models, 12 colors, 3 engine sizes, and 2 transmission types. a) How many distinct Buicks can be manufactured? b) If one of the available colors is blue, how many different blue Buicks can be manufactured?

Short Answer

Expert verified
a) 288 distinct Buicks can be manufactured. b) 24 different blue Buicks can be manufactured.

Step by step solution

01

Count distinct Buicks

In order to find out how many distinct Buicks can be manufactured, multiply the number of ways each feature can vary:Models: 4Colors: 12Engine sizes: 3Transmission types: 2Using the counting principle, the number of possible combinations can be found by multiplying each of these counts together: \(4 \times 12 \times 3 \times 2 = 288\)
02

Count blue Buicks

When considering only blue cars, since there's only 1 way to choose the color, the multiplication changes. Substitute the 'Colors' parameter by 1 and proceed as before:Models: 4Colors: 1 (only 'blue' is considered)Engine sizes: 3Transmission types: 2Using the counting principle again, the number of possible combinations now is: \(4 \times 1 \times 3 \times 2 = 24\)

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Understanding the Counting Principle in Combinatorial Mathematics
In combinatorial mathematics, the counting principle is a fundamental concept used to determine the number of possible outcomes in different scenarios. This principle is particularly useful when calculating the total number of combinations of items or features. For example, when considering how many different types of Buicks can be manufactured, the counting principle helps us understand that we can multiply the number of choices for each feature to find the total number of possibilities.

The counting principle works by considering each feature independently. In the example of Buick cars, there are four distinct features: models, colors, engine sizes, and transmission types. Each feature has a set of distinct options. By multiplying the number of options available for each feature, we find the total number of unique combinations of features.
  • Models: 4 options
  • Colors: 12 options
  • Engine Sizes: 3 options
  • Transmission Types: 2 options
Altogether, this gives us a total number of distinct Buicks as calculated by the product of these options, which is 288. This principle is a straightforward and efficient way to manage complex combinations in problems involving choice and configuration.
Exploring the Concept of Combinations
The concept of combinations is integral to solving problems that involve selecting items from a set without regard to the order in which they are selected. Combinations focus on the selection process where we care about which items are picked, not the sequence in which they are arranged.

In the context of our exercise with Buick automobiles, combinations help us understand how various selections of features like color, model, and engine size can be combined to produce distinct vehicles. For example, if you only want to consider blue-colored Buicks, you focus exactly on how to combine the other features (model, engine size, transmission) with the color blue.

By replacing the 12 color options with just 1 (representing blue), and by multiplying the available options for the other features, we determine that there are 24 different ways to configure a blue Buick. This demonstrates how combinations can be narrowed or adjusted by changing specific criteria, such as the color in this case, to suit particular demands or preferences.
Approaching Problem Solving in Mathematics
Problem solving in mathematics often involves breaking down a problem into manageable parts and applying mathematical principles to arrive at a solution. The exercise of determining the number of distinct Buicks showcases how this can be achieved.

To effectively solve such a problem, it is vital to:
  • Identify the different factors or features involved, such as models, colors, engine sizes, and transmission types.
  • Apply the appropriate mathematical principle, like the counting principle, to calculate the possible combinations.
Start by analyzing what is being asked. For instance, when calculating the total number of configurations for a car, it’s important to understand each feature’s role and how they contribute to the end result.

Next, if specific conditions are given, such as calculating options for only blue cars, adapt the solution by modifying the component associated with that condition. Here, the color options are reduced to one.

Such methodical approaches ensure that the solution is not only accurate but also clear, helping to develop skills in critical thinking and problem resolution. Embracing these steps in problem-solving mathematics can turn complex tasks into simpler, more manageable ones.
