A watermelon weighs 8,475 grams. A scale measured the weight with an error of 12% under the actual weight. What was the measured

7458 grams

find 12% of 8,475 which is 8475*0.12=1017

this just subtract that from 8475 which is 7458

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 %
