The probability of one of the marbles being white is 6/16=3/8 so the probability of both of the marbles being white is (3/8) x (3/8)

Jen's answer assumes that the first marble drawn is then returned to the bag.
If we simply draw two marbles, one after the other, the prob of the stated event is
6/16*5/15
= 1/8
