Question

in how many ways can 4 people can be selected from a group of 6 among which anil is one.how many of these include anil

Answer 1

Solution :-

We have to include Anil in every group. So, Anil is constant in every group. Remaining persons are 5 and we can select only 3 out of them, as we need a group of 4 people. 

We have to apply permutations and combinations logic here. 

⇒ 4 people out of 6 can be selected in following ways = 5!/(5! - 3!)*3!

⇒ (5*4*3*2*1)/(2*1*3*2*1)

⇒ 120/12

= 10 ways
