![How could someone show me how to get the first and 2nd moment. Please and thank you.
Solution
differentiate with respect to t to get first moment and differentiate first moment with
respect to t to get the second moment my(t)= [pe^t +(1-p)]^n my'(t)=n [pe^t +(1-p)]^(n-1) *
pe^t my"(t)=npe^t[pe^t +(1-p)]^n-1 + npe^t * (n-1) * [pe^t +(1-p)]^(n-2) * pe^t](https://image.slidesharecdn.com/howcouldsomeoneshowmehowtogetthefirstand2ndmoment-230403030154-a81d7a5a/85/How-could-someone-show-me-how-to-get-the-first-and-2nd-moment-Pleas-pdf-1-320.jpg)
