- Does a distribution exist for which:Mx(t) = (t)/(t-1)for |t| < 1? If yes, find it, otherwise prove that is not possibleSuppose that f(x, t) is the probability of getting x suc-cesses during a time interval of length t when (i) the probability of a success during a very small time intervalfrom t to t + t is α · t, (ii) the probability of more thanone success during such a time interval is negligible, and (iii) the probability of a success during such a time inter-val does not depend on what happened prior to time t. (a) Show that under these conditions d[f(x, t)]dt = α[f(x − 1, t) − f(x, t)] (b) Show by direct substitution that a solution of thisinfinite system of differential equations (there is one foreach value of x) is given by the Poisson distribution withλ = αt.Let X be a continuous random variable with a pdf f(x) = { kx5 0≤x≤1, 0 elsewhere Determine the value of k.

F(x) denotes the cdf of X.Is the following bounded or unbounded and why? f(x,y) = ln(x2 + y2)Suppose X has the B(20, 0.5) distrubution. Using normal approximation for X with the continuity correction calculate the P(x ≤ 10)
- g is continuous function at q=7, with g(7)= 0. Hence,Suppose that f(x, t) is the probability of getting x successes during a time interval of length t when (i) the probability of a success during a very small time interval from t to t +t is α · t, (ii) the probability of more than one success during such a time interval is negligible, and (iii) the probability of a success during such a time inter-val does not depend on what happened prior to time t. (a) Show that under these conditions f(x, t +t) = f(x, t)[1−α · t]+f(x−1, t)α · t and hence that d[f(x, t)] dt = α[f(x−1, t)−f(x, t)] (b) Show by direct substitution that a solution of this infinite system of differential equations (there is one for each value of x) is given by the Poisson distribution with λ = αt.Prove that the rv Y=(tan^-1(X1/X2)) and Z=(X1^2+X2^2)^0.5 are independent. No distribution is given.
