Question

Explain why this is the correct answer

Suppose U={1,2,3,4,5,6,7,8} is the universal set, and P={1,3,5,7} What is P1

Correct answer is: {2,4,6,8}

why is it correct

Answer 1

do you mean what is \( P^{-1} \)
?
It looks like "P1" is not P
which by definition is U - P
(i.e. start with U and take out anything that is in P, what's left over is not P)

Answer 2

yes

Answer 3

I think yo mean P ' , the little apostrophe mark means "complement of P"
and that means
start with U and take out anything that is in P,
what's left over is the "complement of P"

also called "not P"
