Question

L.11) Sums of independent random variables a) If X1 , X2 X, , , Xn are independent random variables all with Exponential μ distribution, then what is the distribution of XII + 2 +X3 + .tX b) If X is a random variable with Exponential[u] distribution, then what is the distribution of x +X1? c) If X1 , X2 , Х, , , X are independent random variables all with Normal 0. I distribution, then what is the distribution of X +X + X + X ? d) If X is a random variable with Normal[0, 1] distribution, then what is the distribution of Xi +X11 ? rating function for L. 12) The gene a X + b) You have a continuous random variable X and have gone to the trouble of calculating its generating function: Xhigh a) Explain this If a and b are constants, then the generating function of (a X+ b) is: ebt GXat] b) Is the same thing true for discrete random variables?
