Need help asap, tyvm

If an event is independent, we must have that 

P(A) * P(B)  = P(A and B )

So

(.15) *(.35)  = .0525    not equal to P(A and B )    so  the first is dependent

(.15) * (.20)  = .03    = P (A and B)   so independent

(.45) * (.20) = .09  = P (A and B)   so independent

(.25) * (.10)  = .025  not equal to P (A and B)   so  dependent
