YOU SAID:

To 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 = ∑ x P ( x ) .

INTO JAPANESE

離散確率変数 X の期待値、E(X)、または平均 μ を求めるには、単純に確率変数の各値にその確率を掛けて、その積を加算します。式は E ( X ) = μ = ∑ x P ( x ) として与えられます。
