Match the addition and subtraction problems to their solutions: __5/7-3/7 a. 1/24 __1/6+3/6 b. 2/7 __1/2+1/4 c. 2/3 __1/5+1/2 d. 7/10 __1/6-1/8 e. 3/4

5/7 - 3/7 = 2/7   B

1/6 + 3/6 = 4/6 = 2/3   C

1/2 + 1/4 = 2/4+ 1/4 = 3/4    E

1/5 + 1/2 = 2/10 +5/10 = 7/10  D

1/6 - 1/8 = 4/24 - 3/24 = 1/24  A

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 %
