Using the form of the gamma function of Exercise 6.8, we can write And hence Change to polar coordinates to evaluate this double integral, and thus show that (12 ) = v p. In exercise If X is the total we roll with a pair of dice, for which the probability distribution is given on page 63, find the probability distribution of the remainder we get when the values of X are divided by 3. If the probability density of X is given by And Y = X2, find (a) The distribution function of Y; (b) The probability density of Y. If X1 and X2 are independent random variables having binomial distributions with the respective parameters n1 and θ and n2 and θ, show that Y = X1 + X2 has the binomial distribution with the parameters n1 + n2 and θ. Let X and Y be two continuous random variables having the joint probability density Find the joint probability density of Z = X + Y and W = X.Post your question
