What is the standard deviation of a dice roll?

WebbAis the number of dice to be rolled (usually omitted if 1). Xis the number of faces of each dice. For example, if a game calls for a roll of d4 or 1d4, it means "roll one 4-sided die." If the final number is omitted, it is typically assumed to be a six, but in some contexts, other defaults are used. 3d6 would mean "roll three six-sided dice." WebbIf the dice is rolled 1,000 times, the percentage of times a 1 is rolled will fall within the 15% to 18% range, and will eventually converge to 16.7% (1/6). In a fair roll of two dice, there are 36 possible combinations. The probability of rolling a 2 (1 + 1) is 2.8% (1/36).
