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
