Niome is starting a business knits and stitches. she needs cutting someone's blanket sheet. they ask for a medium amount. she tried 3/4 but they said it was too small. then she tried 1 1/2 they said it was too small then she tried 1/2 it was too big. how much could this person want?

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 %
