5. A total of n balls are tossed into 10 bins as follows: each ball is tossed independently and has an equal probability of 0.1 of falling into Bin i, i = 1,2,..., 10. Let Y denote the number of balls in Bin 1. Let Z denote the total number of balls in Bins 6-10. (a) Determine the pmf of Y. Hint: Think binomial distribution. (b) Determine the pmf of Z. (c) Determine the conditional pmf p(zly). Clearly specify the range of y and z. (d) Determine the conditional pmf p(y|z). Clearly specify the range of y and z.
