If the probability of a marksman hitting a target is 90% and he shoots 100 bullets at the target, which of the following must be true there is a 90% probability that the marksman will hit the target half of the time . ? There is a 50% probability that the marksman will hit the target 90% of the time ? The marksman is more likely to hit the target 90 times than any other number of times? None of...

An archer is given five arrows and is told to shoot at a target until he has hit the target or has used up the five arrows. The probability of a hit on each shot is 0.8, independently of the other shots. Let the number of arrows used by the archer be represented by the random variable X. a) (6 points) Find the probability mass function of X. b) (6 points) What is the probability that the archer has to...

Barbara and Diane go target shooting. Suppose that each of Barbara’s shots hits a wooden duck target with probability p 1 , while each shot of Diane’s hits it with probability p 2 . Suppose that they shoot simultaneously at the same target. If we learn that the wooden duck is knocked over (indicating a hit), what is the probability that (a) both shots hit the duck? (b) Barbara’s shot hit the duck? What independence assumptions have you made?

A basketball player attempts 22 shots from the field during a game. This player generally hits about 29% of these shots. (a) In order to use a binomial model for the number of made baskets, what assumptions are needed in this example? Are they reasonable? (b) How many baskets should you expect this player to make in the game? (c) If the player hits more than 11 shots (12, 13, 14, or 22), should you be surprised? (d)...

A baseball player, Mickey, who bats 310 (or .310) gets an average of 3.1 hits in ten at bats. We will assume that each time Mickey bats he has a 0.31 probability of getting a hit. This means Mickeys at bats are independent from one another. If we also assume Mickey bats 5 times during a game and that x= the number of hits that Mickey gets then the following probability mass function, p(x), and cumulative distribution function F(x) are...
