Fifteen percent of all births involve Cesarean (C) section. Ninety-eight percent of all babies survive delivery, whereas when a C section is performed the baby survives with probability 0.96.

(a) Make a tree diagram and mark the given information on the appropriate paths of the diagram. (Note that the probabilities for certain paths are not given.)

(b) What is the probability that a baby will survive delivery if a C section is not performed? (Hint. Use the tree diagram and the remaining information given to set up an equation.)
