Suppose U = {1,2,3,4,5,6,7,8}, Is the Universal set, and P = {1,2,3,4}, What is P'?
1. {5,6,7,8}
2. {1,2,3,4,5,6,7,8}
3.{1,2,3,4}
4. cannot be determined
P' refers to the complement of set P, which consists of all the elements in the universal set U that are not in P.
Since U = {1,2,3,4,5,6,7,8} and P = {1,2,3,4}, the complement of P (P') would be {5,6,7,8}.
Therefore, the correct answer is 1. {5,6,7,8}.
