Suppose U={1,2,3,4,5,6,7,8,9,10} is the universal set and M={7,8,9,10}. What is M'?

A. {1,2,3,4,5,6}
B. {1,2,3,4,5,6,7,8,9,10}
C. cannot be determined
D. {7,8,9,10}
My answer is D.

What is it?

it is A. All of the numbers in that set are numbers that are NOT in M, meaning that M' would be A. ^_^

It is A

IS IT A? IDIOTS!

Thanks toby, really cool!

I suppose it may or may not be A, well then we shall all suffer... for now...

M' means the complement of M.

M' will encompass all the elements in the universal set but NOT in the set M.

So please give it another try.
