Homework Answers

Answer #1

A.

Total # of people = 4+5+6+3 = 18

Now from 18 people, we need to select 5 people for committee.

This can be done in C(18, 5) ways = 8568

So total number of ways of forming committee = 8568

B.

First let's select 2 faculty from a group of 4. This can be done in C(4, 2) = 6

Now we are left with 16 people and we need to select 3 from it. This can be done in C(16, 3) ways = 560

So total different committee possible = 6*560 = 3360
