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>

Answer: the price of one ticket is $70.
Step-by-step explanation:
The family of four went to a theme park and spent the total of $480 on tickets, food, and souvenir.
1/6 of their money was spent for souvenirs . It means that the amount of money that was spent on souvenirs is
1/6 × 480 = $80
1/4 of their money was spent for food. It means that the amount of money that was spent on food is
1/4 × 480 = $120
Total amount spent on souvenirs and food is
120 + 80 = $200
Total amount spent on tickets is
480 - 200 = $280
Since they are 4, the price of one ticket would be
280/4 = $70
