Conditional probability of derangements and fixed points [PDF]

open access: yesTransactions on Combinatorics, 2023
The probability that a random permutation in $S_n$ is a derangement is well known to be $\displaystyle\sum\limits_{j=0}^n (-1)^j \frac{1}{j!}$. In this paper, we consider the conditional probability that the $(k+1)^{st}$ point is fixed, given there are ...
