Question:

With reference to Definition 4.4, show that µ₀ = 1 and that µ₁ = 0 for any random variable for which E(X) exists.

Definition 4.4

The rth moment about the mean of a random variable X, denoted by µ_r, is the expected value of ( X – µ)^r, symbolically

For r = 0, 1, 2, . . . , when X is discrete, and

When X is continuous.
