Question

56% of all newly released films in theaters are animated movies. But just because a film is animated doesn’t mean it’s necessarily suitable for children. Of these animated movies, 29% of them are rated R. For all non-animated movies, 70% are rated R. (It may be helpful to use a probability tree to answer the questions below.)

Use a probability tree to answer the following questions:
