Consider an 7-sided coin and suppose that on each flip one of the sides appears side i
Question:
Consider an 7-sided coin and suppose that on each flip one of the sides appears side i with probability P., numbers r,,n,, let N, denote the number of flips required until side i has appeared for the n, time, i = 1,.,r, and let N = min N, P. 1 For given Thus N is the number of flips required until side i has appeared n, times for some 1, r
(a) What is the distribution of N,?
(b) Are the N, independent? Now suppose that the flips are performed at random times generated by a Poisson process with rate A 1 Let 7, denote the time until side i has appeared for the n, time, i = 1,,r and let T = min T 1-1. F
(c) What is the distribution of T,"
(d) Are the 7, independent?
(e) Derive an expression for E[T]
(f) Use
(e) to derive an expression for E[N]
