You clearly have one chance out of six to make the correct call, while having a 5/6 probability of losing.
In other words, you must try to predict whether the dice will show 1, 2, 3, 4, 5 or 6. Suppose a guy offers you to bet on the outcome of dice roll. Expected Profit = (Potential Net Gain * Probability of Winning) – (Potential Loss * Probability of Losing)
