Question

If N = {positive integers} and subset C = {positive odd integers), what is C′?

{2, 4, 6, 8, …}

{ }

{0, 1, 2, 3, 4, …}

{1, 3, 5, 7, …}

Answer 1

N is stupid and has nothing to do with the problem, so ignore it. They just want the definition of C: positive odd integers.

Answer 2

Got it?

Answer 3

Yah So what next? after i forget about the N

Answer 4

Find C. In other words, find the set with POSITIVE ODD INTEGERS <----definition of C

Answer 5

{1, 3, 5, 7, …} ? :)

Answer 6

If N = {all real numbers} and subset S = {multiples of 4 less than zero}, what is S′?

{multiples of 4 greater than zero}

{even numbers less than zero}

{odd numbers less than zero}

{all real numbers excluding multiples of 4 less than zero}
