comment Joint density of order statistics $f_{X_{(1)}X_{(n)}}(x,y)$ with combinatorics
@Did: Could you please explain the $-\dfrac{\partial^2}{\partial x\partial y}$ part? I am unable to see why that is so.

comment Time to absorption and fraction of time spent in a state in a CTMC
Thanks @Did. I have added some explanation. The 1st point is about expected time to absorption and the second is on expected fraction of time spent in each state prior to absorption (given an initial state).

comment Why is $\sum x^2 _t \times \text{Var}(\beta)=\frac{\sum x^2 _t \times \sigma^2}{ \sum x^2 _t} = \sigma^2$?
What is the context? What is $\beta$?
