The probability of rolling a 3 is 1/6.
The probability of rolling a 7 is 0%.
The probability of rolling a 3 or 4 is 1/3.
The sides on a dice are 1, 2, 3, 4, 5, and 6. They all have a 1/6 chance of rolling.
So,
There is a 1/6 chance of rolling a 3.
There is a 1/3 chance of rolling a 3 or 4.
Since there is no 7 on a dice, there is a 0% chance of rolling it.
