The accompanying tree diagram represents a two-stage experiment. (Let x = 0.45, y = 0.55, r = 0.65, s = 0.35, t = 0.4, and w = 0.6.)

Use the diagram to find the following probabilities. (Round your answers to three decimal places.)

(a) Find P(A) · P(D | A).

(b) Find P(B) · P(D | B).

(c) Find P(A | D).
