Talk:Moment Generating Function of Geometric Distribution/Formulation 1/Examples/First Moment

I get this:

which is not the same as $\dfrac {p e^t } {\paren {1 - p e^t} }$

What am I doing wrong here? I can't see my mistake. --prime mover (talk) 14:45, 20 April 2021 (UTC)

 * No wait - it's ok - $\paren {1 - p e^t}$ cancels
 * Nope - it's wrong - will fix. --Robkahn131 (talk) 15:26, 20 April 2021 (UTC)
