The Game of Band or Bump

In this report we generalize the game of Book or Band described in Levin (2024) to an arbitrary playing deck with $m$ ranks and $s$ cards in each rank, for a total of $t=ms$ cards. Two events (a band or a bump) are defined in terms of given non-negative integers $0\le l\le u \le s$, not necessarily with $l+u=s$. We derive expressions for the joint stopping time distribution and outcome band or bump in terms of rectangular event probabilities for central multiple hyper-geometric random variables.
