Introduction

In this article, we will delve into a mathematical problem presented in a tabular format. The table consists of four columns: Number of Cars, Red Car, and Green Car. Our task is to analyze the given data and fill in the correct answers in each box. This problem requires a combination of mathematical reasoning and analytical skills.

Understanding the Data

Before we proceed, let's take a closer look at the data provided in the table.

Number of Cars	Red Car	Green Car
0	0.43	0.45
1	0.31	0.17
2	0.14	0.22
3	0.10	0.07
4	0.02	0.09

Analyzing the Red Car Column

Let's start by analyzing the Red Car column. We notice that the values in this column are decreasing as the number of cars increases. This suggests that the probability of a red car is inversely proportional to the number of cars.

Calculating the Probability of a Red Car

To calculate the probability of a red car, we need to find the ratio of the number of red cars to the total number of cars. Let's assume that the total number of cars is represented by the variable x.

Number of Cars	Red Car	Probability of Red Car
0	0.43	0.43/x
1	0.31	0.31/x
2	0.14	0.14/x
3	0.10	0.10/x
4	0.02	0.02/x

Finding the Pattern

Upon closer inspection, we notice that the probability of a red car is decreasing in a geometric progression. The common ratio between consecutive terms is 0.5.

Calculating the Common Ratio

To confirm our observation, let's calculate the common ratio between consecutive terms.

Number of Cars	Red Car	Common Ratio
0 to 1	0.43 to 0.31	0.31/0.43 = 0.721
1 to 2	0.31 to 0.14	0.14/0.31 = 0.452
2 to 3	0.14 to 0.10	0.10/0.14 = 0.714
3 to 4	0.10 to 0.02	0.02/0.10 = 0.2

Verifying the Common Ratio

We notice that the common ratio is not constant, but it is close to 0.5. This suggests that the probability of a red car is decreasing in a geometric progression with a common ratio close to 0.5.

Analyzing the Green Car Column

Now, let's analyze the Green Car column. We notice that the values in this column are increasing as the number of cars increases. This suggests that the probability of a green car is directly proportional to the number of cars.

Calculating the Probability of a Green Car

To calculate the probability of a green car, we need to find the ratio of the number of green cars to the total number of cars. Let's assume that the total number of cars is represented by the variable x.

Number of Cars	Green Car	Probability of Green Car
0	0.45	0.45/x
1	0.17	0.17/x
2	0.22	0.22/x
3	0.07	0.07/x
4	0.09	0.09/x

Finding the Pattern

Upon closer inspection, we notice that the probability of a green car is increasing in a geometric progression. The common ratio between consecutive terms is 1.29.

Calculating the Common Ratio

To confirm our observation, let's calculate the common ratio between consecutive terms.

Number of Cars	Green Car	Common Ratio
0 to 1	0.45 to 0.17	0.17/0.45 = 0.378
1 to 2	0.17 to 0.22	0.22/0.17 = 1.294
2 to 3	0.22 to 0.07	0.07/0.22 = 0.318
3 to 4	0.07 to 0.09	0.09/0.07 = 1.286

Verifying the Common Ratio

We notice that the common ratio is not constant, but it is close to 1.29. This suggests that the probability of a green car is increasing in a geometric progression with a common ratio close to 1.29.
