Explanation / Answer

Total members=6+8+15+7=36

The probability that exactly two seniors will be among the officers=

= (7 2) * (29 3)

=21*3654

=76734

The probability that exactly two seniors will be among the officers is 76734.

b)

the probability that at most two of the officers will be freshmen

=(6 1) * (30 4) + (6 2)*(30 3)

=6*27405 +15* 4060

=225330

the probability that at most two of the officers will be freshmen is 225330
