`A cap A'=.............`

A cap B

A cap C =______.

A cap B= phi then B cap A= …………..

A cap B= phi then n (A cap B)=………..

Find sets A, B and C such that A cap B, B cap C and A cap C are non-empty sets and A cap B cap C= phi .

Let A, B and C be three sub-sets of a universal set U, If A' cap C = B' cap C and A cap C' = B cap C' , then

If n(mu )= 40, n(A' cap B')= 6 , n(A cap B')= 10 and n(B cap A)= 16,"then find" n(A cap B)

Give examples of three sets, A,B, C such that A cap B ne phi , (B cap C) ne phi, (A cap C) ne phi and (A cap B cap C) = phi .

If A, B and C be sets. Then, show that, A cap (B cup C) = (A cap B) cup (A cap C) .
