Participants in a study of a new medication received either medication A or a placebo. Find P(placebo and improvement). 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 a placebo, 62% reported no improvement... Please help, I have absolutely NO clue how to go about this. Maybe walk me through it? I don't just want the answer, please.
