Question

Look at the attendance figures shown in the table below. Volley Ball Rugby 7s Junior Athletics attendance figure < 12s 700 500 2,400 12s ≤ attendance figure < 21s 1,000 1,000 2,250 21s ≤ attendance figure < 65s 3,050 2,500 3,350 attendance figure ≥ 65s 250 1,000 2,000 A seat is selected at random for the Fan Camera, which shows crowd reactions during the event. What is the probability that the Fan Camera will show someone the age of 12 or older, but less than 21, during the Volley Ball game? Give your answer as a decimal.

Answer 1

.25 pretty sure this is it, if not yolo

Answer 2

Hence, the probability that the fan camera show someone the age of 12 or older but less than 21 during the volleyball game is: 0.2.

Explanation:

volleyball Rugby 7s junior athletics

attendance figure<12s 700 500 2400

12s ≤attendance figure<21s 1000 1000 2250

21s≤attendance figure<65s 3050 2500 3350

attendance figure≥65s 250 1000 2000

TOTAL 5000 5000 10000

we need to find the probability that the fan camera show someone at the age ≥12 but <21 during the volleyball game

`Probability=(x)/(y)`

where x is the number of people in volleyball in the age group of
`\geq 12` but
`<21` =1000

and y= total number of person in the volleyball group=5000

`Probability=(1000)/(5000)=(1)/(5)=0.2`

Hence, the probability that the fan camera show someone the age of 12 or older but less than 21 during the volleyball game is: 0.2.
