The probability that all 4 are teachers is  0.0000135.

How to solve for the probability

The total number is =

4 + 30 + 4

= 38

The committee of 4 from 38 =

38C4 = 73815

The committee of 4 from 4 teachers =

4C4 = 1 way

The total favorable cases = 1 way

Probability = favorability/ total cases

= 1/73815

= 0.0000135

Hence the probability that all 4 are teachers is 0.0000135.
