If A= `{x : 2x + 1, x in N, x le 5}`,
B = {x: x is a composite number, `xle 12`},
then show that `(A cup B) - (A cap B) = (A - B) cup(B -A)`.

A cup (B cap C)= ………..

A cup B = A cap B then……………

IF A={x:x in N, x lt 10 }, B={x:x is a prime number and x lt 10 }, then show that A-B ne B-A with the help of Venn-diagram.

If A={4,5,6},B={7,8} then show that A cup B=B cup A .

n(A)=2,n(B)=7, n(A cap B)=1 and n (A cup B) ?

A = {x : x in R, x ge 2}, B = {x : x in R , x lt 4} " then " A cap B =

If A = { x : x is a factor of 15} , B = { x : x is a factor of 18} , then A cap B =

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

F A={x:x is a natural number}, B={x:x is an even number}, C={x:x is an odd number}, D={x:x is a prime number} then find A cup B, A cap B, B cap C and B cap D .

IF A= {x :x in N and x lt20} and B= {x :x in N and x le 5} , then write the set A-B in the Set-Builder form.
