From a group of 6 people, you randomly select 4 of them.
What is the probability that they are the 4 oldest people in the
group?
Give your answer as a fraction
Ans:
Total possible ways to choose 4 people from 6 is=6C4
There is only one way to choose the 4 oldest.
P(choosing 4 oldest)=1/6C4=(4/6)*(3/5)*(2/4)*(1/3)
=24/360
=6/90
=1/15
