Suppose that 15% of the time Tucker goes swimming twice a week 25 % of the time he goes swimming once a week, and 60% of the time he doesn't go swimming at all in a given week. What is the expected value for the number of times Tucker goes swimming during a week?

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 %
