Now you have one less marble in the bag, and we're assuming that the first pick was green, so you only have two green marbles left. And so what does this give us for our total probability? Well, let's see, 3 5ths times 2 4ths. Well, 2 4ths is the same thing as 1 half. This is going to be equal to 3 5ths times 1 half, which is equal to 3 tenths. Or we could write that as 0.30. Or we could say there's a 30% chance of picking two green marbles when we are not replacing.
