Question

rom a group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas. What is the probability that Marnie and Noomi are both selected?

Answer 1

probability that Marnie and Noomi are both selected=0.1

Explanation:

A group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas.

the possibility of selecting 2 from 5 manages is 5C2 ways

`5C2= (5!)/(2!(5-2)!) =10`

There is only one choice of selecting Marine and Noomi from 5 managers

So probability of selecting Marine and Noomi is

`(1)/(10) =0.1`
