After doing nearly all the coursework for a Ph.D. in math, I then did all the coursework for a Ph.D. in statistics and completed that degree.

comment Find and sample minimum of two exponential distribtions
It's not clear what you mean by $\arg\min$ in this case.

comment Find and sample minimum of two exponential distribtions
Your assertion about the distribution of $\min\{X_1,X_2\}$ is right if $X_1,X_2$ are independent. ${}\qquad{}$

comment Can't figure out $O(n \log n)$ divide-and-conquer algorithm
I also changed"$\text{...}$" to "$\ldots$". Also standard. ${}\qquad{}$

comment Can't figure out $O(n \log n)$ divide-and-conquer algorithm
I changed $O(n$ $log$ $n)$ to $O(n\log n)$, coded as O(n\log n). That is standard usage. Proper spacing automatically results, as does non-italiciziation of $\log$. Your way of providing spacing was weird. ${}\qquad{}$

I changed $<a,b,c,\ |\ b^2,(bc)^2>$ to $\langle a,b,c,\mid b^2,(bc)^2\rangle$. That is standard usage.

Probably this is better posted to stats.stackexchange.com than here.
