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

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

$Probability=\frac{x}{y}$

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

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

$Probability=\frac{1000}{5000}=\frac{1}{5}=0.2$

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.
