My Professor of Stochastic Processes gave us this challenge to be able to exempt the subject, but I cant solve it. Stochastic Processes TOPICS: Asymptotic Properties of Markov Chains May 25, 2019 1.Consider the stochastic process R-fRnh defined as follows: Where {Ynjn is a succession of random variable i.i.d (Independent random variables and identically distributed), with values in {1,2, ...^ with Ro 0 a) Why R is a Markov Chain? Find the state space of R b) Find the transition...

My Professor of Stochastic Processes gave us this challenge to be able to exempt the subject, but I cant solve it. Stochastic Processes TOPICS: Asymptotic Properties of Markov Chains May 25, 2019 1.Consider a succession of Bernoulli experiments with probability of success (0,1),we say that a streak of length k occurs in the game n, if k successes have occurred exactly at the instant n, after a failure in the instant n-k We can model this event in a stochastic...
A topological space X has the Hausdorff property if cach pair of distinct points can be topologically scparated: If x, y E X and y, there exist two disjoint open sets U and U, with E U and y E U and UnU = Ø.

1. Consider a fair four-sided die, with sides 1, 2, 3, and 4, that is rolled twice. For example, "1,4" would indicate 1 was rolled first and then 4 was rolled second a) Write down the possible outcomes, i.e., the sample space. (b) List the outcomes in the following events: Event A: The number 4 came up zero times. Event B: The number 4 came up exactly one time. . Event C: The sum of the two rolls is odd...
