Find A ∩ B if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.
Ø
{7}
{3, 4, 5, 7, 9, 10, 13, 17}

The answer to your question is {7}.

Step-by-step explanation:

Data

A = { 4, 7, 10, 13, 17}

B = {3, 5, 7, 9}

The symbol ∩ means intersection and means that the result is the set of elements that have in common two or more sets.

In this problem, ∩ means the elements that belongs to A and B.

-Comparing both sets we notice that the only element that belong to A and B is {7}.
