Question

If A= {x:x is a natural number},B= {x:x is an even natural number
C= {x:x is an odd natural number and D= {x:x is a prime number
Find AnB, AnC, AnD, BnC, BnD, CnD.​

Answer 1

A = {1,2,3,4,5...}

B = {2,4,6,8,10...}

C = {1,3,5,7,9,11...}

D = {2,3,5,7,11...}

AnB = {2,4,6,8,10...} = B

AnC = {1,3,5,7,9,11...} = C

AnD = {2,3,5,7,11...} = D

BnC = null

BnD = {2}

CnD = {3,5,7,11,13...}
