Let X be a fınite random variable on asample space S, letX(S) = {x1, 22,..., æn},and letf(x;) = P(X = x;),where i = 1, 2,..., n be the distribution ofX. Then the expected value (mean) E(X)of X, also written as ux, is defined by(choose all correct variants):Select one or more:а.b. II-1 ti f(x;)c. Irex(s) ªf(x)d. x1f(x1) + ... + ænf(xn)e.
