WebbIf XX and YY are independent, then we can multiply the probabilities, by Theorem 7.1 : P(X = x) ⋅ P(Y = y). But P(X = x)P (X = x) is just the marginal distribution of XX and P(Y = y)P (Y =y) the marginal distribution of YY. So this is equal to: fX(x) ⋅ fY(y) Let’s calculate another marginal distribution—this time from the formula ...
