. Let A = {x/x is positive integer that is divisible by 2}. B = { x/x is a positive integer that is
divisible by 3}. C = {x/x is appositive integer that is divisible by 5}. List the elements of the
sets A, B, C. Find (a) A∩ (B∩C) and (b) (A∩B) ∩C. Show that A∩ (B∩C)= (A ∩ B) ∩ C
.Let A = {x/x is a positive integer less than 7} and B = {x/x is an integer land -3 ≤ x ≤4}.
List the number of A and B, and then write down A ∪ B.
