If `A = {x: x` is prime number, `x < 7`), `B {x:x ` is even number, `2 leq x leq 8}` , `C = {x: x` is natural number and `x < 5}` Then find `A+ B` and `A nn (B-C)`

For each of the following pairs of sets , identify the disjoint and overlapping sets: A = { x: x is a prime number , x lt 8 } B = {x: x is an even natural number , x lt 8 } .

If A = { x//x is a prime number and x B = { x//2x+1, x in w and x A-B

If A = { x//x is a prime number and x B = { x//2x+1, x in w and x AnnB

If A = { x//x is a prime number and x B = { x//2x+1, x in w and x BnnA

If A - {x|x is a prime number and x B = {x|2x + 1, x in w and x Find BnnA ?

Let A = { x : x is a prime number and x lt 30 } The number of different rational numbers whose numerator and denominator belong to A is :

If A = { x//x is a prime number and x B = { x//2x+1, x in w and x B-A. What do you observe?

Consider the sets A and B given by A = {x:x is a natural number, 2lexle6 } B = {x:x is a prime number x le7 } C = {x : x^2-5x+ 6 = 0} Write A,B and C in the roster form.

Consider the sets A and B given by A = {x:x is a natural number, 2lexle6 } B = {x:x is a prime number x le7 } C = {x : x^2-5x+ 6 = 0} Verify that (AbigcupB)bigcupC=Abigcup(BbigcupC)
