Question
The number of ways in which three persons can dress themselves when they have 4 shirts. 5 pants and 6 hats between them, is-
- 4C3 × 5C3 ×6C3
- 4P3× 5 P3 × 6 P3
Hint:
Here, we can use the formula

The correct answer is: 4P3× 5 P3 × 6 P3
Given that,
Shirts = 4 , Pants = 5 and Hats = 6, which are distributed among 3 men.
For shirts, Number of ways they can wear = 
For pants, Number of ways they can wear = 
For hats, number of ways they can wear = 
Total number of ways they can wear

Thus, the number of ways in which three persons can dress themselves when they have 4 shirts. 5 pants and 6 hats between them, is
.

A tea party is arranged of 16 persons along two sides of a long table with 8 chairs on each side. 4 men wish to sit on one particular side and 2 on the other side. In how many ways can they be seated ?
Whenever we face such types of problems the key point is to make special arrangements for the people who are in need of it, then arrange the remaining. Now combination comes with permutation as there are possibilities of these 8 people sitting on one side to rearrange. Thus this concept into consideration, to get through the answer.
