a. Explain the difference between the method of moment generating function and the method of incarnation to find the probability density function of a random variable
b. Let X1, X2, X3 ,,,,, each of them has Poisson distribution with parameter lamda 1, lamda2, lamda3,........
i. Get the probability distribution of Y=X1+X2+....Xn
ii. Get the mean and variance of Y
c. Y1 and Y2 be a joint probability function as shown below in the screenshot imageU=Y1/(Y1+Y2), Using the method of incarnation (Jacobian), find the probability density function of U
