Participants in a study of a new medication received either medication A or a placebo. Find P(placebo and improvement). You may
find it helpful to make a tree diagram of the problem on a separate piece of paper.
Of all those who participated in the study, 80% received medication A.
Of those who received medication A, 76% reported an improvement.
Of those who received the placebo, 62% reported no improvement.
I don't know how to do this at all, any hints or help would be nice. :)
