Some fireworks were projected vertically into the air from the ground at an initial velocity of 80 feet! per second. The function modeling the path of the fireworks is given as
h(t) = -16+2 + 80t where h represents the height of the fireworks t seconds after launch. How long where the
fireworks in the air before returning to the ground?

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 %
