Trying to use a decimal model to show 0.1×0.7= ? the model grid is 10 by 10

7

Step-by-step explanation: the answer is 7 because 0.1 is actually 1 and 0.7 is actually 7 so it is 1 times 7 and that equals 7

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 %
