answered If $x \leq g(x) \leq x^2-x+1$ where $x \in [0,2]$, can we say that $g(x)$ is continuous at $x=1$?

@RHS - this is not a rewrite to your question. the hints are in the last paragraph. Note that the word "dearrange" is a link to guide you do find the number of permutations without fixed points

comment question about summation?
I think its $m-t+1$. If you sum from $1$ to $2$ you have $(2-1)+1$ elements in the sum

OK, but The answer still depends on how many people you have

How many people do you have ? if $X$ is discrete then he doesn't have a density function, maybe you are looking for the distribution ?

Thanks! this is much simpler. What does noting that $G$ is simply connected gives us ?
