Question

If A = the set of composite numbers less than 16, B = the set of factors of 16. Find A ∩ B. *​

Answer 1

Answer:

4, 6, 8, 9, 10, 12, 14, 15, 16 = Set A

1, 2, 4, 8 and 16. = Set B

A ∩ B = 4,8,16

Answer 2

Answer:

A ∩ B =  {4,8}

Step-by-step explanation:

Given,

A = the set of composite numbers less than 16

B = the set of factors of 16

To find

A ∩ B

Solution:

Recall the concepts:

A ∩ B is the set of all numbers that are common to both A and B.

Since A is the set of composite numbers less than 16, we have

A = {4,6,8,9,10,12,14,15}

Since B is the set of factors of 16,

B = {1,2,4,8,16}

The elements that are common to A and B = {4,8}

A ∩ B =  {4,8}
