I&#x27;m not sure that it makes a difference in this case, but it is insufficient in situations such as these to look at just the expected return. A rational agent&#x27;s actions are determined by <i>expected utility</i>, which could be highly non-linear depending on myriad factors such as the player&#x27;s net worth. i.e. it could be rational to trade a lower chance of the largest payoff for a more consistent payoff of a lesser but still substantial amount, even at the cost of a significantly smaller expected return.
