In a yahtzee roll, calculate the probability of
Chance
Probability of Chance = Probability of No Scoring Rolls
Probability of Chance = All Possible Roll Scenarios - All Winning Scenarios
Probability of All Winning Scenarios = Yahtzee + 4 of a kind + Full House + Lg St . Sm St + 3 of a kind
Probability of All Winning Scenarios = 1/1,296 + 25/1,296 + 25/648 + 5/162 + 10/81 + 25/162
Probability of All Winning Scenarios = 476/1,296
All Possible Roll Scenarios = 6 faces per die for 5 dies
All Possible Roll Scenarios = 6 * 6 * 6 * 6 * 6
All Possible Roll Scenarios = 7,776
All Possible Roll Scenarios - All Winning Scenarios = 1 - 476/1,296
Probability of Chance = | (1,296 - 476) |
1,296 |
Probability of Chance (Nothing) = | 820 |
1296 |
Using our GCF calculator, we reduce top and bottom by 4, to get
Probability of Chance (Nothing) = | 205 |
