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

Got it?

Yah So what next? after i forget about the N

anonymous · Answer

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

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}
