Answer 1

Step-by-step explanation:

1. 21 ,24,27,30
2. 23,29,31
3. 22,24,26,28,30

Answer 2

Answer:

The members of set C are: 20, 22, 24, 26, 28, 30, 32.

The members of the intersection of set A and set C is: 24, 30.

Step-by-step explanation:

From the above question,

They have given :

          A = multiples of 3 between 20 and 32

          B = odd numbers between 20 and 32

          C = even numbers between 20 and 32

a) list the members of A ∪ B

The union of set A (multiples of 3 between 20 and 32) and set B (odd numbers between 20 and 32) is the set of all elements that are members of either set A or set B, or both.

The members of set A are: 21, 24, 27, 30.

The members of set B are: 21, 23, 25, 27, 29, 31.

The members of the union of set A and set B is: 21, 23, 24, 25, 27, 29, 30, 31.

b) list the members of A ∩ C

The intersection of set A (multiples of 3 between 20 and 32) and set C (even numbers between 20 and 32) is the set of all elements that are members of both set A and set C.

The members of set C are: 20, 22, 24, 26, 28, 30, 32.

The members of the intersection of set A and set C is: 24, 30.
