Let X have a Poisson distribution with parameter . Show that E(X) = directly from the definition

Question:

Let X have a Poisson distribution with parameter . Show that E(X) = directly from the definition of expected value. [Hint: The first term in the sum equals 0, and then x can be can- celed. Now factor out and show that what is left sums to 1.]
