Suppose U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set, and P = {2, 4, 6, 8, 10}. What is p'?

The complement of set P, denoted as P', is the set of all elements in the universal set U that are not in set P.

In this case, set P = {2, 4, 6, 8, 10}. Therefore, set P' will contain all the elements in U that are not in P.

To find P', we can subtract set P from set U:
P' = U - P = {1, 3, 5, 7, 9}

So, P' = {1, 3, 5, 7, 9}.
