Answer:
<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>
Step-by-step explanation:
In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group
P(O)= <em>favorable number of outcomes / total number of outcomes </em>
<h3>= 1 / 11C4</h3>
= 11! / (11-4)! 4!
= 7! *4! / 11!
=1/ 130
<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>
