1/2 of the class has blonde hair and 1/4 the class has black hair.1/4 of the class has brown hair if there are 32 kids in the class how many kids have each hair color

Step-by-step explanation:

so there is 32 kids1/2 are blonde, 1/4 have black hair, 1/4 have brown hair

1/2(32) = 32/2 = 16 are blonde

1/4(32) = 32/4 = 8 have black hair

1/4(32) = 32/4 = 8 have brown hair

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 %
