Answer to Question 1

A combination of strategies is a Nash equilibrium if each player chooses a strategy that is a best response to the strategies of others. This means that when the players are in a Nash equilibrium, no player in the game will be able to change his strategy and improve his or her payoff.
In a Nash equilibrium each player has chosen a best response to the strategies the other players have chosen. In a dominant strategy equilibrium each player has chosen a strategy that is a best response to any strategy the other players could have chosen. So, while a dominant strategy equilibrium is also a Nash equilibrium, a Nash equilibrium is not necessarily a dominant strategy equilibrium.

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
