n(AnB)=10

n(AnB')=7

4) A={X∈Z-, -5

Set A containing in the set of all X which is an element of negative integers where X is greater than -5 and less than +2.

b) Elements of A:

{-4,-3,-2,-1,0,1}

c) Finite

5) If u={x| x∈ Z, 0≤ X ≤ 15}, A={multiples of 3 less than 16}, B={prime numbers less than 16} list the element of :

A: { 0, 3,6,9,12,15}

B: { 2,3,5,7,11,13}

B'={0,1,4,6,8,9,10,12,14,15}

AUB ={0,2,3,5,6,7,9,11,12,13,15}

AnB'={0,6,9,12,15}

Question: Is 0(Zero) a infinite or finite number?
