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

1 answer

Q' is the complement of set Q, which means it includes all the elements in the universal set U that are not in set Q.

To find Q', we subtract set Q from the universal set U.

Q' = U - Q

In this case, set U consists of the numbers from 1 to 10, and set Q consists of the numbers 3, 6, and 9.

So, Q' includes all the numbers from 1 to 10 except for 3, 6, and 9.

Therefore, Q' = {1, 2, 4, 5, 7, 8, 10}.
