Solution:
To form a committee of 5 persons including exactly 3 teachers, we need to select 3 teachers and 2 students.
Number of ways to select 3 teachers:
We have 4 teachers and we need to select 3 of them. This can be done in ^4C3 ways = 4 ways.
Number of ways to select 2 students:
We have 16 students and we need to select 2 of them. This can be done in ^16C2 ways = 120 ways.
Therefore, the total number of ways to form a committee of 5 persons including exactly 3 teachers is:
4 × 120 = 480.
Hence, there are 480 ways in which the committee can be formed.
