Suppose U = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set and Q = {3, 6, 9). What is Q"?
mario62 [17]

Answer:

\{3, 6, 9\}

Step-by-step explanation:

U is the universal set, that is, a set that contains the universe of possible sets, which is formed by 10 elements in this. Q is a subset of U formed by three elements: 3, 6, 9. (Q \subseteq U)

Q'' represents the complement of the complement of Q. The complement of Q is the subset of U formed by elements not contained in Q. which simbolized by Q'. That is, 1, 2, 4, 5, 7, 8, 10.

The complement of Q' corresponds to the elements contained in Q. Hence, the correct answer is \{3, 6, 9\}.
