Suppose that one box contains 201 long bolts and 323 short bolts ,and that the other box contains 505 long bolts and 412 short bolts. Suppose also that one box is selected at random and a bolt is then selected at random from that box. Find the probability that this bolt is long. *

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
