yes
The probability of rolling a number less than 6 on a die would be 5/6.
On a normal cube, the probability is 0. If there are more than 1 cubes, the answer depends on how many are being rolled for each sum.
Zero
Assuming these are regular dice, the probability is 1.
It is 1/6.
It is 15/36.
1/12
The probability is 0.277... (repeating).
1/6 because the other numbers don't affect the probability
With a single cube, the probability is 100%With two cubes, the probability is 15/36 = 5/12 = 412/3 %
It is 1.
4/6
