Given the sets M = {5, 6, 7, 8, 9} and N = {6, 8, 10, 12, 14}, the set M∩N is identified by which notation below?

A- {6, 8}

B- {5, 6, 6, 7, 8, 8, 10, 12, 14}

C- {5, 6, 7, 8, 9, 10, 12, 14}

D- ø

Answer 1

The symbol ∩ means the "intersection" of two sets. In other words, it is the set of terms that are found in both sets. In the case of M∩N, the only common terms are {6,8}, making choice A the correct answer.
