I need the step-by-step solution for this question.

If X and Y are aleatory independent variables with a Poisson distribution whose parameters are $\lambda_1$ and $\lambda_2$, respectively. Show that the aleatory variable $W=X+Y$ has a Poisson distribution too.

I was adding a long comment to your conditional expectation problem when it got deleted! – copper.hat Jun 19 '19 at 19:40
Sorry, I thought that maybe I had forgotten to put a detail. – Jun 19 '19 at 19:43
I didn't notice that was another same question. I understand now how to do it. – Jun 19 '19 at 19:51
@RebecaSilva I'm pleased about that. – callculus42 Jun 19 '19 at 19:54
