A store sells ground meat in small, medium, and large sizes. The weights of the small size packages have a mean weight of 1 pound in a standard deviation of 0.1 pound. If the distribution of weights for the small size packages of ground meat is approximately normally distributed, which of the following is the best estimate of the probability that a random selected small size package has a weight less than 0.9 pounds? A.) 0.025 B.) 0.16 C.) 0.32 D.) 0.68

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 %
