4. A particle performs a symmetric random walk in two dimensions starting at the origin: eachstep is of unit length and has equal probability of being northwards, southwards, eastwards, orwestwards. The particle first reaches the line x + y = m at the point (X, Y) and at the time T. Findthe probability generating functions of T and X - Y, and state where they converge.

Based on the provided information, it is clear that the particle first reaches the line x+y=m at the…

Exercise 3 This exercise looks at the "signal detection" problem in lecture (Fri 2/3) from the per- spective of odds. Recall the set-up: a signal X is sent with probability X = +1 with probability p with probability 1-p for some 0 < p < 1. A noise Z~ N(0,1) is added to the signal during the process of transmission, so that the signal received is Y = X + Z. (i) Compute the prior odds of X = +1 to X = -1. (ii) Suppose we receive Y = y. Compute the likelihood ratio (a.k.a. Bayes factor) fy(y X = +1) fy (y X = -1) as a function of y. When is this greater than, equal to, and less than 1, respectively? (iii) Compute the posterior odds of X = +1 to X -1 as a function of y. When is this greater than, equal to, and less than the prior odds, respectively? =

A system component has malfunctioned, and the delivery time, Y, of a new part is uniformly distributed on the interval of 0 to 3 days; i.e. it can arrive at anytime over the next three days. The system must be shut down until the new part arrives. The cost incurred (in thousands of dollars) due to this interruption is C = 5 + 2Y². a. Find the probability that the cost incurred due to the interruption is less than $13,000. (Hint: Think in terms of days or use P(g(Y) < c) = P(Y < g¬l(c)).) b. Find the expected value of C. c.

Please do not give solution in image formate thanku. Consider a particle moving on a one-dimensional line along discrete locations . . . , −2, −1, 0, 1, 2, . . . . Assume that the particle starts at location 0 at time t0 = 0 and it makes a step at every discrete time ti of length 1. A step to the right occurs with probability p and any step is independent of all previous steps. What is the probability that the particle returns to the origin after N steps? How does this probability behave for large N for a special case of p = 1/2?
