Step-by-step explanation:

We have to list the elements present in each set.

A = {multiples of 3 between 20 and 32}

A = {21, 24, 27, 30}

B = {odd numbers between 20 and 32}

B = {21, 23, 25, 27, 29}

C = {even numbers between 20 and 32}

C = {20, 22, 24, 26, 28, 30, 32}

a) list the members of A ∪ B

This means to select the elements of sets A and B

A ∪ B = {21, 23, 24, 25, 27, 29, 30}

b) list the members of A ∩ C

This means to only pick the elements that are present in both A and B

A ∩ C = {24, 30}
