Question
and nts 1. Exene takes four basketball free-throws in a row. She is successfal on ench one ind with probability 4/5. You can (and in fact, should!) leave your answers unsimplified on this question. Tht (a) his question. That is pt to simplify it. 0, leave your answer in this form and don't attem ) What's the probability that she makes all of her shots? What's the probability that she makes at least one shot? ) What's the probability that in order, her sequence of shots is success, miss, miss, succes (d) What's the probability that she misses her last two shots? is present in a mouse, then it has probability 9 of making it through a given If gene HNFIA t the probability is only .6. In a mouse selected at random from the population probability .2. What is the probability that the mouse can make it whether the scenario could occur impossible.Explanation / Answer
a) probability of making all her shots =(4/5)4
b) probability that she makes at least one shot =1-P( probability of making no shot) =1-(1-4/5)4 =1-(1/5)4
c)probability of given sequence =(4/5)*(1/5)*(1/5)*(4/5) =42/54
d)probability that misses last two shots =(1/5)*(1/5) =(1/5)2
