Question

Suppose U = {1,2,3,4,5} is the universal set and A = {2,3}. What is A?

Answer 1

Isn't A already given?

Answer 2

Oh sorry. I meant A'

Answer 3

Okay, so

A' are all the elements of U that are not in A

Answer 4

In other words

A' = U - A

Or the elements of U minus the elements of A

Answer 5

OK. So the answer would be {1,4,5}?

Answer 6

Correct A' = {1, 4, 5}

Answer 7

OK. Thanks
