Answer 1

B.{20,21,22,23,24,25,26,27,28,29,30,31,33}

Answer 2

S = {20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35}
A = {20,22,23,24,26,28,30}
B = {23,24,25,27,29,31,33}
C ={21,23,25,27,29,31,33}

A n B = {23,24}
A U C = {20,21,22,23,24,25,26,27,28,29,30,31,33}
B° ={20,21,22,26,28,30,32,34,35}
A - B ={20,22,24,26,28,30}
n(A - B) = 6
