1/6 assuming a standard 6 sided dice.
1 out of 6
Combinations and permutations
The probability of not rolling a 6 is 5/6.
a 2 out of 6 probability
rolling a die? 5/6
If it is a fair die, the probability is 5/6.
The probability is 1/6 x 5=5/12
5/6
Prob[Not rolling a 5] = 1 - Prob[Rolling a 5] = 1 - 1/6 = 5/6.
The probability of rolling a multiple of five on a standard die is 1 in 6, or about 0.1667.The probability of rolling a 10, 15, or higher is zero, because the question implied only one die.
The probability of rolling at least one 2 when rolling a die 12 times is about 0.8878. Simply raise the probability of not rolling a 2 (5 in 6, or about 0.8333) to the 12th power, getting about 0.1122, and subtract from 1.

First calculate the probability of not rolling a six - since there are 5 possibilities for each die, this is (5/6) x (5/6). Then calculate the complement (1 minus the probability calculated).First calculate the probability of not rolling a six - since there are 5 possibilities for each die, this is (5/6) x (5/6).
