Suppose a geyser has a mean time between eruptions of 77 minutes. Let the interval of time between the eruptions be normally distributed with standard deviation 25 minutes. What is the probability that a randomly selected time interval between eruptions is longer than 88 ​minutes?

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 %
