Question

Suppose U= {0,1,3,5,7,9} is the universal set and A= {1,3,7}. What is A?

Answer 1

you are told what A is

Answer 2

Is it really that simple?

Answer 3

You mean A' ?

Then it is everything in the universal set that is NOT in A, so it is A' = {0,5,9}

Answer 4

maybe you are being asked for \(A'\) or \(A^c\) or \(\overline{A}\) the "compliment of A"

Answer 5

I meant A' thank you!
