Problem 10E

The pdf of X is f (x) = c/x2, 1 < x < ∞.

(a) Calculate the value of c so that f (x) is a pdf.

(b) Show that E(X) is not finite.

Step-by-Step Solution:

Step 1 of 3:

Given that the probability density function of X is f(x)=,1<x<

We have to calculate the value of c and show that E(X) is not finite.
