Introduction

In this article, we will explore the concept of probability in the context of forming a student-faculty government committee. The committee consists of 4 members, and we are given 24 student volunteers and 5 faculty volunteers. Our goal is to find the probability that the committee will consist of all faculty members. This problem involves the concept of combinations and probability, which are fundamental in mathematics.

Calculating the Total Number of Possible Committees

To begin, we need to calculate the total number of possible committees that can be formed from the 24 student volunteers and 5 faculty volunteers. Since the committee consists of 4 members, we can use the combination formula to calculate the total number of possible committees. The combination formula is given by:

C(n, k) = n! / (k!(n-k)!)

where n is the total number of items, k is the number of items to choose, and ! denotes the factorial function.

In this case, we have 29 total volunteers (24 students + 5 faculty), and we want to choose 4 members for the committee. Therefore, the total number of possible committees is:

C(29, 4) = 29! / (4!(29-4)!) = 29! / (4!25!) = 24,310

Calculating the Number of Committees with All Faculty Members

Next, we need to calculate the number of committees that consist of all faculty members. Since there are 5 faculty volunteers, and we want to choose 4 members for the committee, the number of committees with all faculty members is:

C(5, 4) = 5! / (4!(5-4)!) = 5! / (4!1!) = 5

Calculating the Probability of All Faculty Members

Now that we have calculated the total number of possible committees and the number of committees with all faculty members, we can calculate the probability of all faculty members being on the committee. The probability is given by:

Probability = (Number of committees with all faculty members) / (Total number of possible committees) = 5 / 24,310 = 1 / 4,862

Conclusion

In this article, we calculated the probability of a student-faculty government committee consisting of all faculty members. We used the combination formula to calculate the total number of possible committees and the number of committees with all faculty members. The probability of all faculty members being on the committee is 1 / 4,862, which is approximately 0.000206.

Discussion

This problem involves the concept of combinations and probability, which are fundamental in mathematics. The combination formula is used to calculate the total number of possible committees, and the probability is calculated by dividing the number of committees with all faculty members by the total number of possible committees. This problem can be extended to more complex scenarios, such as calculating the probability of a committee consisting of a certain number of students and faculty members.

Applications

This problem has applications in various fields, such as:

Politics: In the context of forming a government committee, this problem can be used to calculate the probability of a certain group of people being on the committee.
Business: In the context of forming a team or committee, this problem can be used to calculate the probability of a certain group of people being on the team.
Statistics: This problem can be used to calculate the probability of a certain event occurring, which is a fundamental concept in statistics.
