How do you get the double sum or integral from E(X+Y)E(X+Y) (expected value)? Ask Question Asked 4 years, 3 months ago Modified 3 years, 7 months ago Viewed 964 times 3 I was given a proof for E(X+Y)E(X+Y) = E(X)+E(Y)E(X)+E(Y) for cases where...
We call the proposed model the probabilistic minisum FIP (PMFIP); it involves minimizing the sum of the expected distance that each flow travels until intercepted at a facility among placed facilities. This extension allows us to evaluate the effect of facility location under any given value of ...
The expected value of the random variable may or may not belong to the range of the random variable. Answer and Explanation:1 Given PMF of the random variable X forx=1,2,3,4.is {eq}\begin{align*} &P\left( {X = 2} \right) = 0.1\&P\left( {X = 3} \...
Let X be a random variable having pmf p(x) = dfrac{sum^6_{n=1}begin{pmatrix}6\ nend{pmatrix{2^6} ,,x = 0,1,2,3,4,5,6 What is the expected value of X ? Explain how to find the expected value of CDF. A...
