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>

= 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>
