If the payoff matrix of a game is (3642)\begin{pmatrix} 3 & 6 \\ 4 & 2 \end{pmatrix}, find the maximin value of the game.

Worked solution (try it first)
  1. Find the smallest payoff in each row: min⁡(3,6)=3\min(3, 6) = 3 and min⁡(4,2)=2\min(4, 2) = 2.
  2. The maximin value is the largest of these row minima, 3, option D.
