Question

Given the following Venn diagram, choose the correct set for M ∩ N.

{3, 9}

{2, 5, 9}

{4, 7}

Answer 1

M ∩ N means the intersection of M and N, so they are looking for the numbers that are in both M and N.

The numbers that are in both are 4 and 7

The answer is {4,7}

Answer 2

M ∩ N = { 4,7}

Explanation:

M ∩ N

This means intersection, or where M and N overlap

M = { 3 9 4 7}

N = { 4 ,7 ,6}

M ∩ N = { 4,7}
