Qualifying throws: 1/6, 2/5, 2/6, 3/4, 3/5, 3/6, 4/3, 4/4, 4/5, 5/2, 5/3, 5/4, 6/1, 6/2 and 6/3
These represent 15 of the 36 possible throws so probability is 0.417 or 41.7%
The probability of rolling a total of 3 or less on two dice is 3 in 36 or 1 in 12.
certainty (no doubt), probability or likelihood (greater than 50% chance), possibility (greater than 0% but less than 50% chance)
There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.
Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.
There are 2 numbers less than 3, so the probability in this case is 2 in 8, or 1 in 4. There are 3 numbers greater than 5, so the probability in this case is 3 in 8. There are 5 numbers less than 3 or greater than 5, so the probability in this case is 5 in 8.
The probability of rolling a total of 3 or less on two dice is 3 in 36 or 1 in 12.
The probability is zero. No number can be less than 3 and greater than 4.
Probability can not be less than 0 or greater than 1. A probability of 0 means there is no possibility whatsoever of an event occurring. A probability of 1 means that the event is guaranteed to occur no matter what.
It depends on the events. The answer is 0.5*(Total number of events - number of events with probability = 0.5) That is, discount all events such that their probability (and that of their complement) is exactly a half. Then half the remaining events will have probabilities that are greater than their complement's.
No. A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1. 0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.

Probability values are never negative and are always between 0-1 according to the definition Probability of A= Number of outcomes classified as A/Total number of possible outcomes
A joint probability can have a value greater than one. It can only have a value larger than 1 over a region that measures less than 1.
There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.
Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.
There are 2 numbers less than 3, so the probability in this case is 2 in 8, or 1 in 4. There are 3 numbers greater than 5, so the probability in this case is 3 in 8. There are 5 numbers less than 3 or greater than 5, so the probability in this case is 5 in 8.
There are 216 permutations of three dice. Of these, 206 have a sum that is less than 16, specifically, the permutations 466, 556, 565, 566, 646, 655, 656, 664, 665, and 666 have sums that are 16 or greater - all other permutations have sums that are less than 16. The probability, then, of rolling a sum less than 16 on three dice is 206 in 216, or about 0.9537.
