Question

4 people are on the team. Members will be chosen randomly to serve as chairperson, treasurer, secretary, or timekeeper . Noor is hoping to be chairperson and Qu is hoping to be treasurer. What is the probability that Noor is selected to be chairperson and Qu is selected to be treasurer?

Answer 1

Explanation:

Given that four people are on the team. Members will be chosen randomly to serve as chairperson, treasurer, secretary, or timekeeper

Since one person cannot serve two posts we have total number of ways

= 4(3)(2)(1) = 24

If Noor is chair person and Qu treasurer then remaining 2 can take two posts in 2 different ways

So probability that Noor is selected to be chairperson and Qu is selected to be treasurer

=favourable outcomes/total outcomes

=
`(2)/(24) \\=0.083`
