    discrete distribution help!(elementry)



    the question:
    A basketball player has an established practice routine. He does not leave the gym until he has made 5 free throws in a row. the prob that he makes a free throw is 0.85. What is the probability that he leaves after a total of 10 free throws?

    My attempt at the question:

    Binomial dist with n=10, standard deviation(0.85)^5

    he has to lose the first 5 throws so i am assuming the probability is (1-0.85)^5
    and he has to make the next 5 throws so that probability would be (0.85)^5

    i do not know how to go on from here

    Please help!

    THANKS! (:

    Does he really need to miss all of the first five shots?
