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}
