Question

D.

Answer 1

Step-by-step explanation:

total subject = S = 560

football = 320

volleyball = 300

all people like at least one games = 500

i. both games (b)

football only = 320 - b

volleyball only = 300 - b

so

500 = (320 - b) + (200 - b) + b

500 = 320 - b + 200 - b + b

500 = 520 - b

b = 520 - 500 = 20 people

ii. do not like play both games

S - All people like = 560 - 500 = 60 people
