Question

If x is subset of y then X union Y is equal too ​

Answer 1

Answer:

Y

Step-by-step explanation:

If X is a subset of Y it means its as part of Y

Assuming Y is the universal set, if we take union if the two we will get:

X U universal set (Y) = universal set(Y)

This is because universal set Y already covers all the elments in both X and Y. When we take unions we do not repeat elements so,

Y is the answer
