Answer:
Step-by-step explanation:
[tex]W [/tex]∩ [tex]X[/tex] is asking for the intersection of sets [tex]W[/tex] and [tex]X[/tex], or simply, which numbers can be found in both sets.
The numbers shared between the two sets are [tex]3, 4, 5[/tex].
Next, we need to union this result with the set [tex]Y[/tex], or simply, combine the numbers in both sets together.
This would result in [tex]2, 3, 4, 5[/tex]
