From Vanessa: Duels in the town of Discretion are rarely fatal. There, each contestant comes at a random moment between 5 a.m. and 6 a.m. on the appointed day and leaves exactly 5 minutes later, honor served, unless his opponent arrives within the time interval and then they fight. What fraction of duels lead to violence?
There must be a minimum number of 100 trials and things like graphing calculator, dice, spinners, and whatever are allowed.
