Lana had 8 4/6 cups of flour. If she used 6 1/6 cups of flour, how much flour
did she have left?

2 3/6 or 2 1/2

Step-by-step explanation:

8 4/6 - 6 1/6 = 2 3/6

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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 %
