Introduction
In this article, we will explore the concept of probability and how it can be applied to real-world scenarios. We will use a survey of 42 children to determine the probability that a sophomore goes to school by car. The survey results are presented in a table, which will be analyzed to calculate the desired probability.
Understanding Probability
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. In this case, we want to find the probability that a sophomore goes to school by car.
Survey Results
The survey results are presented in the following table:
| Car | Bus | Walk | Total | |
|---|---|---|---|---|
| Year 9 | 8 | 10 | 4 | 22 |
| Year 10 | 6 | 8 | 2 | 16 |
| Year 11 | 4 | 6 | 1 | 11 |
| Year 12 | 2 | 4 | 0 | 6 |
| Total | 20 | 28 | 7 | 42 |
Calculating the Probability
To calculate the probability that a sophomore goes to school by car, we need to find the number of sophomores who go to school by car and divide it by the total number of sophomores.
From the table, we can see that there are 6 sophomores who go to school by car (Year 10). The total number of sophomores is 16 (Year 10).
Therefore, the probability that a sophomore goes to school by car is:
P(Car) = Number of sophomores who go to school by car / Total number of sophomores = 6 / 16 = 0.375
Interpretation of Results
The probability that a sophomore goes to school by car is 0.375, which means that there is a 37.5% chance that a randomly selected sophomore will go to school by car.
Conclusion
In this article, we used a survey of 42 children to determine the probability that a sophomore goes to school by car. We calculated the probability by dividing the number of sophomores who go to school by car by the total number of sophomores. The result is a probability of 0.375, which means that there is a 37.5% chance that a randomly selected sophomore will go to school by car.
Limitations of the Study
There are several limitations to this study. Firstly, the survey was conducted on a small sample of 42 children, which may not be representative of the larger population. Secondly, the survey only asked about the mode of transportation to school and did not collect any other relevant information. Finally, the study did not control for any potential confounding variables that may have affected the results.
Future Research Directions
There are several potential directions for future research. Firstly, a larger and more representative sample could be used to increase the generalizability of the results. Secondly, additional variables could be collected to provide a more comprehensive understanding of the factors that influence the mode of transportation to school. Finally, the study could be replicated in different contexts to see if the results are generalizable.
