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}
