Answer»

Match the following:

Given U is universal set.

A, B are subsets of U.

n(U), n(A), n(B) are no. of elements in U, A, B respectively.

Number of:

(1) Elements neither in A nor in B (A) $n (A \cup B)$

(2) Elements only in A (B) $n (B) - n (A \cap B)$

(3) Elements only in B (C) $n (A) - n (A \cup B)$

(4) Elements either in A (or) in B (D) $n (U) - n (A \cup B)$

(E) $n (A) - n (A \cap B)$
