The length of a game in minutes is a continuous random variable Z, with pmf f(t) = e-t for t > 0 (exponential random variable). You have already sat through t minutes of the game, and are interested in whether the game is about to end immediately or not (hazard rate h(t)). h(t) = f(t)/ (1- F(t)). f(t) = Game ends between time t and time t + dt. (1- F(t)) = Probability the game does not end before time...
