1/6+1/6+1/6-1/6 =.333
The probability of of rolling three ones on three dice is (1 in 6)3, or 1 in 216, or about 0.004630.
(1/6)^3 since each event is independent and each has a probability of 1/6.
The probability of rolling 3 ones with 4 dice is:4C3 (1/6)3 (5/6) = 0.015432098... ≈ 1.54%
( 2 / 36 ) x ( 2 / 36 ) = 0.003086 (rounded)
If the number cubes are standard dice cubes, the odds of rolling 3 ones is 1 in 216.
The probability of rolling 6 ones with 10 dice is: 10C6 (1/6)6 (5/6)4 = 2.170635034...x 10-3 ≈ 0.22%
A standard six-sided die has 3 even numbers and 3 odd ones, so the probability of rolling either an odd or even number would be 50-50.
1/361/6 x 1/6 = 1/36
If you roll the die often enough, the probability of getting a 2 ones in a row is 1. In only 2 rolls, the answer is (1/6)*(1/6) = 1/36
It is approx 0.1974
Probability = (1/6)3 = 1/216 =0.00463
The odds of rolling a single one on a 20-sided die is 1 in 20 (1/20). Since the rolls are independent events, the odds of rolling two ones on two 20-sided dice would be (1/20) * (1/20), which simplifies to 1 in 400 (1/400).
