You are buying a new phone and deciding between 2 phone plans. Plan A charges you a one-time fee of $630 for your phone, and then an additional $40 per month for the service. Plan B will charge you a one-time fee of $350 for your phone, then an additional $60 per month for the service. After how many months will the phone plans be equal in cost

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 %
