That’s a measly one in a billion. Why would you believe that this is enough? Enough for what? I’m talking about the preferences of a foreign agent. We don’t get to make our own rules about what the agent prefers, only the agent can decide that.
Regarding practical purposes, sure you could treat the agent as if it was indifferent between A, B and C. However, given the binary choice, it will choose A over B, every time. And if you offered to trade C to B, B to A and A to C, at no cost, then the agent would gladly walk the cycle any number of times (if we can ignore the inherent costs of trading).
