There are 12 people on the swim team. How many ways can the coach select 3 people to swim in the relay?

There are 12 choices for the first person, 11 for the second and 10 for the third so the answer is 12 * 11 * 10 = 1320.

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 %
