Question

In how many ways can 13 people be divided into four groups with 3, 6, 2 and 2 people respectively?

Answer 1

Total combination = 180,180

Explanation:

It is a combination based problem.

So,

Total people = 13

Group = 3,6,2,2

So,

For 6 people

13C6= 1,716

For 3 people

7C3 = 35

For 2 group of 2 people

(4C2)/2 = 3

Total combination = 1,716 × 35 × 3

Total combination = 180,180
