So for example, if I have a random variable X, take it to be normally distributed.
How do you find the expectation and variance of the random variable e^X in terms of μ and σ?
Integrating the entire normal function with the f(x) is it?
I got a question here, and I am stuck at understanding the step of the solution. Any help will be appreciated.
I would like to know how to get from the second to the third step, where the summation comes in.
It looks like...
Its a question that I had from a friend in the past.
I had tried solving it but to no avail.
Have tried integration and stuff like that, but I think there is an easier way to solve this question.
