Question

If A={2,4,6,8,10,12,14,16}, B= {1,2,3,4,5,6,7,8,9,10} then find (a) AUB

(b)A-B (c)B-A​

Answer 1

Step-by-step explanation:

A - B = [ remove B elements from A]

= [12,14,16]

B - A = [remove A elements from B]

= [ 1,3,5,7,9]

Answer 2

Answer:

AUB = {1,2,3,4,5,6,7,8,9,10,12,14,16}

A-B = {12,14,16}

B-A = {1,3,5,7,9}

Step-by-step explanation:

AUB= {2,4,6,8,10,12,14,16} U {1,2,3,4,5,6,7,8,9,10}

AUB= {1,2,3,4,5,6,7,8,9,10,12,14,16}

A-B= {2,4,6,8,10,12,14,16} - {1,2,3,4,5,6,7,8,9,10}

A-B= {12,14,16}

B-A = {1,2,3,4,5,6,7,8,9,10} - {2,4,6,8,10,12,14,16}

B-A = {1,3,5,7,9}
