Question

A used car saleswoman estimates that each time she shows a customer a car, there is a probability of 0.1 that the customer will buy the car. The saleswoman would like to sell at least one car per week. If showing a car is a Bernoulli trial with a probability of 0.95 of at least one sale, (i) how many cars would the saleswoman show per week? (ii) calculate the probability of exactly three sales per week.

Step 1

Given that the probability of selling a car when showing it is 0.1, the probability of not selling a car is 0.9. The probability of at least one sale in a week is 0.95. Therefore, the probability of not selling any cars in a week is 1 - 0.95 = 0.05. This can be Show more…
