It is 1/3.

On a single roll it is 2/3.

3/6

If you roll the die often enough the probability is near enough 1 so as to make no difference. On a single roll, the probability is 1/2.

It is 1/3.

On a single roll it is 2/3.

Possible outcomes of one roll = 6.Probability of an even number on one roll = 3/6 = 0.5 .Probability of an even number on the second roll = 0.5 .Probability of an even number on the third roll = 0.5 .Probability of an even number on all three rolls = (0.5 x 0.5 x 0.5) = 0.125 = 1/8The probability of at least one odd number is the probability of not gettingan even number on all 3 rolls. That's (1 - 1/8) = 7/8 or 0.875 or 87.5% .

If you roll the die often enough the probability is near enough 1 so as to make no difference. On a single roll, the probability is 1/2.

Let say the dice has n sides Let first search for the probability to roll a number less or equal to 2 Probability to roll a 1 = 1/n Probability to roll a 2 = 1/n Probability to roll a 1 OR a 2 = Probability to roll a 1 + Probability to roll a 2 = 1/n + 1/n = 2/n Probability to roll a number greater than 2 = 1 - (Probability to roll a 1 OR a 2) = 1 - 2/n = (n-2)/n If n = 6 then the result is (6-2)/6 = 4/6 = 2/3

The probability of rolling a total of 3 or less on two dice is 3 in 36 or 1 in 12.
