This chapter focuses on the expectation of random variables, particularly the expectation of elementary random variables. It presents proofs of the Lebesgue's theorem on monotone sequences and the Lebesgue's theorem on term by term integration. The chapter discusses signed measures and the Radon–Nik...
The first property is that if X and Y are the two random variables, then the mathematical expectation of the sum of the two variables is equal to the sum of the mathematical expectation of X and the mathematical expectation of Y, provided that the mathematical expectation exists. In other ...

,Xn are nn random variables such that each expectation E(Xi)E(Xi) is finite (i=0,…,n)(i=0,…,n) ,then E(X1+⋯+Xn)=E(X1)+⋯+E(Xn)E(X1+⋯+Xn)=E(X1)+⋯+E(Xn)证明期望的加法性质,连续双随机变量证明过程如下,其他情况类似: E(X1+X2)=∫−∞...

Assign each probability to its corresponding value of X. Step 4: Multiply each value of X with its associated probability calculated in step 3. Step 5: Sum up the products obtained in step 4 to compute the expectation value for discrete random variables. If X is continuous, integrate the ...
An Accurate, Fast Approximation for the Sum of Fading Random Variables via Expectation Maximization Applications to Diversity Systems Sums of fading envelopes occur in several wireless communications applications. The exact mathematical solution to this statistic is, however, rather intri... Jose David ...
First the binomial random variable is expressed as a sum of n Bernoulli distributed random variables: X = X1 + ··· + Xn. Then since E(Xi) = p for each Xi, the sum evaluates (by Theorem 4.2.3) to np. Recall that Theorem 4.2.3 says: Theorem 4.2.3 If X1 + ··· + Xn ...
