The answer depens on how many dice are rolled. And since you have chosen not to divulge that critical bit of information, it is not possible to give a more useful answer.
The probability of rolling a number less than 6 on a die would be 5/6.
There is a 4 in 6 (or 2 in 3) probability of rolling a number less than a five on a standard number cube.
The probability is 1.
It is 1.
1:6
The probability of rolling a number less than 1 on a standard 6-sided die is zero. It will not happen.
There could be many questions: What is the probability of rolling an even number. What is the probability of rolling an odd number. What is the probability of rolling a number less than 4. What is the probability of rolling a number more than 3. What is the probability of rolling 1,4, or 6. Basically it could be any question about the probability of rolling half of the faces.

5 over 11
The probability of rolling a number less than 5; which is a 4, 3, 2, or 1 is 4/6 or 2/3. The probability of tossing a head is 1/2. So, the probability of a roll less than 5 and a head is 2/3*1/2 or 1/3 or 0.333. 4/12
The probability of rolling a number on a die is 1 out of the number of sides on the die. So, for a six sided die, the probability of rolling a 4 is 1/6. The probability of rolling a 4 or a 5 becomes 2/6 or 1/3. This is because there are two acceptable outcomes out of six. So when finding the probability of rolling a number less than x on a y sided die, it becomes x-1 / y. It is x-1 because the outcome is to roll less than the number, not less than or equal.
