# Chaitanya's Random Pages

I hail from Melbourne, Australia and like maths and sport.

1. I do like this about page. It’s short (just like mine), but still speaks of a fondness of maths (just like mine).

2. Hello I find the result in https://ckrao.wordpress.com/2012/05/27/the-distribution-of-xxy-is-uniform-when-x-and-y-are-iid-exponential/ interested. However, do you have the pdf of the general case here (the ratio of sum of k exponential variables to the sum of n exponential variables). I am not a math guy. Thank you very much.

• It is the beta distribution with parameters $k$ and $(n-k)$, its pdf is proportional to $x^{k-1}(1-x)^{n-k-1}$. Look up https://en.wikipedia.org/wiki/Beta_distribution for the exact pdf.
