Among a group of five people selected at random from a certain population it is known that the probability that no one will be 35 or over 0.01024. i. What is the probability that exactly one person in the group is under 35? ii. Calculate the mean and variance of the probability distribution of the number of persons over 35 and compare to the formula values for this type of distribution. iii. Given three such groups, what is the probability that two out of three groups have no more than two persons 35 or over?
