Question

The universal set is the set of whole numbers less than 14.

U = {0,1,2,3,4,5,6,7 ,8 ,9 ,10 ,11 ,12 ,13}

Set J is the set that represents the numbers that Janet thinks are lucky.
J={3,7}

Set K is the set that represents the numbers that Kyle thinks are awesome!
K={2,4,6,8}

Set L is the set that represents the numbers that Lauren thinks she should write on the wall of her bedroom (with her parent’s permission, of course)!
L={0,3,5,6,7,8,9}

What is the set defined by ~(J ∪K) ?

Answer 1

~(J ∪K) = not J union K = not {2, 3, 4, 6, 7, 8} = {0, 1, 5, 9, 10, 11, 12, 13}
