Question
Two people enter a bus. Two adjacent cramped seats are
free. Each person must decide whether to sit or stand. Sitting alone is more comfortable than sitting next to the other person, which is more comfortable than standing. Suppose that each person cares only about her own comfort. Model the situation as a strategic game. Find its Nash equilibrium (equilibria?).Solution
There exist only one pure strategy Nash equilibrium (sit, sit) and the argument is same as that of Prisoner’s Dilemma discussed in theory.
A bowl contains 9 blue balls, 7 white, and 5 black balls. If 2 balls are drawn in one go, then the probability of exactly one ball being blue is:
