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

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) .

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

Find the sum of all prime numbers less than 20.

Find the sum of all prime numbers less than 20.

Write all the prime numbers less than 15.

Write all the prime numbers less than 15.

Let A = {Multiples of 3 less than 20} B = {multiples of 5 less than 20 } Then , A cap B

The average of all odd numbers less than 100 is:

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

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:
