mario62 [17]

Answer:

\{3, 6, 9\}

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\}.
