 In Figure 5.1, the payoffs are dependent upon a pair of possible worlds. World \(\omega_1\) occurs with probability \(\mu(\omega_1) = .51,\) while \(\omega_2\) occurs with probability \(\mu(\omega_2) = .49.\) Hence, they coordinate with complete success by both choosing \(A(B)\) only if the state of the world is \(\omega_1(\omega_2)\).
