Proof of a Probability Problem by Induction












1












$begingroup$


Dear Statisticians and Mathematicians,
I am interested in proving the following lemma by induction
enter image description here



I have shown that it holds true for $n=2$ which I don't provide its proof here. We assume it is true when $n$ is replaced by $n-1$. I conditioned on $Y_1+...+Y_{n-1}$ but I could not prove. I don't know how to use the induction hypothesis to prove the lemma. I really appreciate any help of you guys in this regard.

    Are you not satisfied with the proof that Ross provides in the text?

    @Math1000 Actually my adviser and I are looking for a simpler proof.
