If Jill offers Maggie a chocolate from the bag, what is the probability that she randomly picks either a white chocolate or a milk chocolate?

    You're almost there. Convert that 27/40 into a decimal. What do you get?

    Great. Now there's only a probability of 0.4 that the teacher will give out any chocolates at all. So you must multiply your result by that probability of 0.4. What do you get?
