Your Abercrom B men's fashion outlet has a 40% chance of launching an expensive new line of used auto-mechanic dungarees (complete with grease stains) and a 60% chance of staying instead with its traditional torn military-style dungarees. Your rival across from you in the mall, Abercrom A, appears to be deciding between a line of torn gym shirts and a more daring line of "empty shirts" (that is, empty shirt boxes). Your corporate spies reveal that there is a 40% chance that Abercrom A will opt for the empty shirt option. The payoff matrix gives the number of customers your outlet can expect to gain from Abercrom A in each situation.
