Agriculture: Apples Approximately 3.6% of all (untreated) Jonathan apples had bitter pit in a study conducted by the botanists Ratkowsky and Martin. (Bitter pit is a disease of apples resulting in a soggy core, which can be caused either by overwatering the apple tree or by a calcium deficiency in the soil.) Let n be a random variable that represents the first Jonathan apple chosen at random that has bitter pit.
(a) Write out a formula for the probability distribution of the random variable n.
(b) Find the probabilities that n = 3, n = 5, and n = 12.
(c) Find the probability that n ≥ 5.
(d) What is the expected number of apples that must be examined to find the first one with bitter pit?
