A college senate consists of 10 staff members, 12 faculty members, and 4 students. From this group, a disciplinary committee consisting of 2 staff members, 3 faculty members, and 1 student must be chosen to investigate a plagiarism case. How many such committees could be formed?
Number of ways of selecting 2 staff members from the total of 10 staff members
= 10 C 2
= 45
Number of ways of selecting 3 faculty members from the total of 12 faculty members
= 12 C 3
= 220
Number of ways of selecting 1 student from the total of 4 students
= 4 C 1
= 4
Now,
Total number of committees that could be formed
= Number of ways of selecting 2 staff members * Number of ways of selecting 3 faculty members * Number of ways of selecting 1 student
= 45 * 220 * 4
= 39600
