Question 1149936: Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities.
Assume the probability that you will make a sale on any given telephone call is 0.14. Find the probability that you (a) make your first sale on the fifth call, (b) make your sale on the first, second, or third call, and (c) do not make a sale on the first three calls

For each call, the probabilities for making a sale or not are
P(yes) = 0.14
P(no) = 0.86
(a) P(first sale on 5th call) = P(no,no,no,no,yes) =
(c) P(no sales on first three calls) = P(no,no,no) =
(b) P(first sale on first, second, or third calls) = 1 - P(no sales on first three calls) = 1 minus the answer from part (c)
