Expected value of uniform random variable

WebTo find the expected value, E (X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E(X) = μ = ∑xP(x). Here x represents values of the random variable X, P ( x) represents the corresponding probability, and symbol ∑ represents the ... WebNote that given that the conditional distribution of \(Y\) given \(X=x\) is the uniform distribution on the interval \((x^2,1)\), we shouldn't be surprised that the expected value looks like the expected value of a uniform random variable!
