Let X be the length of the initial run in a random ordering of n ones and m zeros. That is, if the first k values are the same (either all ones or all zeros), then X 脷 k. Find E[X].
Consider the following dice game, as played at a certain gambling casino: Playersand roll a pair of dice in turn. The bank then rolls the dice to determine the outcome according to the following rule: Playerwins if his roll is strictly greater than the banks. Forlet
and show that and are positively correlated. Explain why this result was to be expected.
A fair die is rolled times. Calculate the expected sum of the rolls.
Repeat Problem 7.68 when the proportion of the population having a value of less than is equal to .
The number of accidents that a person has in a given year is a Poisson random variable with mean. However, suppose that the value ofchanges from person to person, being equal to for percent of the population and for the otherpercent. If a person is chosen at random, what is the probability that he will have
a. We are required to find
b. We are required to find .
c. Define as the number of accidents in a preceding year. As likely as we are require to find.
