Answer:
Total number of students = 70
Let A be the set of students who likes to play Cricket.
Let B be the set of students who likes to play Kho-kho.
Hence the number of students who likes to play
Cricket or Kho-kho is n (A U B )
n (A U B ) = 70
Number of students who likes to play both Cricket and
Kho-kho = n (A n B)
n (A) = 45, n (B) = 52
We know, n (A U B ) = n (A) + n (B) - n (A n B) .
n (A n B) = n (A) + n (B) - n (A U B )
= 45 + 52 - 70 = 27
Number of students who likes to play both the games are 27,
Number of students who likes to play Kho-kho are 45.
Number of students who likes to play only Cricket = 45 -27 = 18
A n B is the set of students who play both the games.
n (A n B) = 27
