1. evaluate 64 = [4 x (27 - 52).
write the expression.
= [4 x (
find 52
64 = [4 (27 -
subtract
64 = [4 x
multiply
64 =
64
divide.
so, 64 = [4 x (27 - 52)] =
less

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 %
