The probability a telesales representative making a sale on a customer call is .15. Find the probability: a) Her first sale comes after 5 calls. b) Her first 5 calls went with out a sale. What is the probability she will have to make more than 13 calls until her first sale? c) Less than 2 sales are made on 5 calls. Representatives are required to make an average of at least 4 sales a day or they are fired....

Suppose that a basketball player has a 28.31% chance of making any shot they take. If they were to take 34 shots in a given game, we would of course expect them to make 28.31% of them, but what would be the standard deviation in the number of shots made?
