Question

Let U=(0,1,2,3,4,5...) A=(1,2,3,4...) B=(4,8,12,16...) and C=(2,4,6,8...) Determine the following A' U but it is turned the other way C

Answer 1

A' U ?

Answer 2

It should be shaped like a rainbow I can't find the symbol on my keyboard

Answer 3

A' union with what?

Answer 4

C

Answer 5

first find A'

Answer 6

I think "A' U but it is turned the other way" means: \(\overline{A}\cap C\)

Answer 7

yes

Answer 8

Since \(\overline{A}\) and \(C\) have no elements in common, the intersection is \(\emptyset\)

Answer 9

oh intersection

Answer 10

A'={0}
C={2,4,6,8,......}

so, A' int C = {phi}
(i.e. elements present both in A' and C)

Answer 11

thanks
