Answer 1

Answer:

Step-by-step explanation:

$W$∩ $X$ is asking for the intersection of sets $W$ and $X$, or simply, which numbers can be found in both sets.

The numbers shared between the two sets are $3, 4, 5$.

Next, we need to union this result with the set $Y$, or simply, combine the numbers in both sets together.

This would result in $2, 3, 4, 5$
