Question: If the probability density of X is given by Where k
If the probability density of X is given by
Where k is an appropriate constant, find the probability density of the random variable Y = 2X / 1+ 2X . Identify the distribution of Y, and thus determine the value of k.

(a) Use the result of Example 7.2 to find the probability density of Y = | X|. (b) Find the probability density of Z = X4(=Y4). If X1 and X2 are independent random variables having the geometric distribution with the parameter θ, show that Y = X1 + X2 is a random variable having the negative binomial distribution with the parameters θ and k = 2. 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.
