Answer:
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.
Step-by-step 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
[tex]Probability=\frac{x}{y}[/tex]
where x is the number of people in volleyball in the age group of [tex]\geq 12[/tex] but [tex]<21[/tex] =1000
and y= total number of person in the volleyball group=5000
[tex]Probability=\frac{1000}{5000}=\frac{1}{5}=0.2[/tex]
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.
