Question

A = {1, 3, 5, 7, 9) B = {2, 4, 6, 8, 10) C = {1, 5, 6, 7,9} A U (B n C)= ?

Answer 1

Answer:

{1, 3, 5, 6, 7, 9}

Step-by-step explanation:

A u (B n C)

First we look at

(B n C)

n indicates intersects. Intersects means the common. The common number in B and C, we have

{6}

Now A u {6}

u means union. That is, joining both sets together, hence, we have

{1, 3, 5, 6, 7, 9}

A u (B n C} gives {1, 3, 5, 6, 7, 9}
