Robert uses his calculator to generate 5 random integers between 1 and 9 inclusive.
i. Find the probability that at least 2 of the 5 integers are less than or equal to 4.
Robert now generates n random integers between 1 and 9 inclusive. The random variable X is the number of these n integers which are less than or equal to a certain integer k between 1 and 9 inclusive. It is given that the mean of X is 96 and the variance of X is 32.
ii. Find the values of n and k.
