Are you looking for **Let X have mass function f(x)={_{0}^{{x(x+1)}-1} . If x=1, 2, …, otherwise, and let α ∈ R. For what values of α is it the case that E(X^{α}) < ∞ Answer**? If yes, here is the correct answer to this question asked in the NPTEL Introduction To Machine Learning Assignment. The correct answer of Let X have mass function

*f(x)={*. If x=1, 2, …, otherwise, and let α ∈ R. For what values of α is it the case that

_{0}^{{x(x+1)}-1}*E(X*is marked in green color with a tick sign.

^{α}) < ∞Let X have mass function *f(x)={ _{0}^{{x(x+1)}-1}* . If x=1, 2, …, otherwise, and let α ∈ R. For what values of α is it the case that
