IF A={Prime numbers less than 10}, and B={positive odd number less than 10}, then find (i) A`cap` B (ii) B-A.

If A={Positve perfect squares less than 100} and B={Positve perfect cuber less than 100} , then find n(A cap B)

If mu = {set of natural numbers less than 20 }, A = {factors of 18} and B= {odd numbers less than 15}, then find (i) (A nn B)' , (ii) A' uu B'

A={all primes less than 20} B={ all whole numbers less than 10} then A cap B =…………

If A is the set of positive divisors of the number 18;B is the set of prime numbers less than 12, and C is the set of even natural numbers less than 10, then (A uu B)nn C is

If A = {x : x is a prime less than 20} and B = {x : x is a whole number less than 10}, then verify n(A uu B) = n(A) + n(B) - n(AnnB) .

Let A={x: x is a positive multiple of 3 less than 100} and B={x: x is a prime number less than 20}, then n(A) + n(B) is equal to:
