1/1, 1/2, 1/3, 2/1, 2/2, 3/1 = 6 out of 36 ie 16.66%
The probability is 3/6 or 1/2
If rolling 1 die it is 1; if rolling 7 dice it is 0.
The answer depends on how many dice are in the SET of dice.
The probability is 1, if the dice are rolled often enough.
5 over 11
Assuming you're using 6-sided dice, The probability of rolling less than 4 on one die is 1/2. To roll 3 dice and get less than 4 on 2 (and only 2) of them is 3/8.
1:6
The probability is 1, if the dice are rolled often enough.
4/6 or 2/3
2/6
The problem can be split into two parts, rolling a 12, or rolling a 4 or less. This can be further broken down to rolling a 2, rolling a 3, rolling a 4, or rolling a 12. P(rolling 4 or less, or 12) = P(rolling 4 or less) + P(rolling 12) = P(rolling a 2) + P(rolling a 3) + P(rolling a 4) + P(rolling a 12) = 1/36 + 2/36 + 3/36 + 1/36 = 7/36
