Question

If S = {positive integers} and subset T = {positive integers divisible by 3}, what is T'?

Answer 1

T ' means the set of everything in S but NOT in set T

basically the complete opposite of set T

Answer 2

T = {positive integers divisible by 3}

T ' = {positive integers NOT divisible by 3}

example: {3, 6, 9, 12, ...} is in set T
T ' would have the numbers {1,2,4,5,7,8,...}
