## Homework Equations

[/B]

P(X∈A,Y∈B)=P(X∈A)×P(Y∈B)

## The Attempt at a Solution

If X and Y are independent then:

P(X∈A,Y∈B)=P(X∈A)×P(Y∈B)

I am confused how I can find P(X∈A) and P(Y∈B) .

I tried doing 0.1 * 0.2 = P(X∈A)

and 0.9 = (P(Y∈B))

and multiply those to get .018, but that is inccorect.
