Hope this helps.

Answer 2

Did you mean P' ? The letter P with a tick mark after it. If so, then start with set U and erase any number you find in set P

We start with
{1,2,3,4,5,6,7,8}
and we erase the following: 1,2,3,4
since those numbers are in set P

P = {1,2,3,4}
P ' = {5, 6, 7, 8}

The set P' is the complement of set P. It is, in a sense, the opposite of set P. It contains everything that P doesn't have.
