Assume that the masses of adult men can be modelled by the Normal distribution with mean 75 kg and standard deviation 5 kg.
The probability that an adult man, chosen at random, will have a mass greater
than 77.5 kg is
(4 d. p.)
The probability that an adult man, chosen at random, will have a mass between
76.6 kg and 83.5 kg is
(4 d. p.)
62% of adult men have a mass greater than
kg (1 d. p.)
The interquartile range for the masses of adult men is
kg (1 d. p.)

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

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 %
