Given : 7 students like to play Basketball
8 like to play Cricket.
3 students like to play on both Basketball and Cricket
To Find : How many students like to play Basketball or Cricket or both
Solution:
n( B) = like to play Basketball = 7
n( C) = like to play Cricket = 8
n ( B ∩ C) = like to play both = 3
n ( B U C) = like to play Basketball or Cricket or both
n ( B U C) = n(B) + n(C) - n ( B U C)
=> n ( B U C) = 7 + 8 - 3
=> n ( B U C) = 12
Hence 12 Players like to play Basketball or Cricket or both
