Out of 3 people to be selected , one of them is a male employee.

The number of ways to select male employee = 1

The 2 other members of committee can only be selected from 5 female employees.

Number of ways of selecting 2 other members among 5 female employees = 5C2 = \(\frac{5!}{3!2!}*1 = 10\)

Total number of ways = ways of selecting 2 female members * ways of selecting 1 male member = 10 * 1 =10

Answer is A

An office has 6 employees; there are 5 female employees and 1 male employee. In how many ways can a 3-person committee be created if the committee must include the male employee?

A) 10
B) 12
C) 15
D) 24
E) 30


In order to ensure that the 3-person committee includes the male employee, we'll start by placing the male employee on the committee.
Our task now is to choose 2 more people (from the 5 female employees) to join the male on the committee.

Since the order in which we select the two people does not matter, we can use combinations.
We can select 2 employees from 5 employees in 5C2 ways (= 10 ways)

Answer: A
