One of the measures of the effectiveness of a stimulus is how much the viewers pulse rate increases on exposure to it. In testing a lively music theme for its television commercials, an advertising agency shows ads with the new music to 25 viewers and their mean pulse rate is 20.5 beats per minute while the mean pulse rate per minute for a comparable sample of 25 viewers seeing the same ads with the old music was 16.9 beats per minute. Is the new music theme better

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 %
