Question

From a group of 9 people, you randomly select 5 of them.

What is the probability that they are the 5 oldest people in the group?

Give your answer as a fraction

Answer 1

There are 9C5 ways to select 5 people from a group of 9 people = 126

There is only 1 group with 5 oldest people

Therefore, probability = 1/126
