Question

A stadium holds a total of 7,500 people. A random survey of 150 people finds that 17 of them are under 21 years old.

Enter the total number of people predicted to be in the stadium under 21.

Answer 1

Answer: 850 people

Explanation:

Stadium capacity = 7,500 people.

A random survey was done for 150 people and it was found out that 17 of them are under 21 years old. This can be expressed as a fraction as:

= 17/150

The total number of people that are predicted to be in the stadium of under 21 will be:

= 17/150 × 7500

= 17 × 50

= 850 people
