Question

Given the two sets, what is A ∩ B ?

A = {1, 2, 3, 4, 5, 6}

B = {2, 3, 5, 7}

Answer 1

2, 3, 5

Explanation:

A∩B means "A intersection B" which includes all elements that are shared in BOTH sets. This would be the middle crossover section of a Venn diagram.

Hence, 2 and 3 and 5 are shared in both sets.
