The RV N takes values in the non-negative integers. Show that N has mean satisfying E(N)-ΣP(N> k), k=0 whenever this series converges. Each packet of the breakfast cereal Soggies contains exactly one token, and tokens are available in each of the three colours blue, white and red. You may assume that cach token obtained is equally likely to be of the three available colours, and that the (random) colours of different tokens are independent. Find the probability that, having searched the contents of k packets of Soggies, you have not yet obtained tokens of every colour. Let N be the number of packets required until you have obtained tokens of every colour. Show that E(N)= 11/2.
