Not always because probability has a range from 1 to 0

No. Probability is always represented as a positive ratio/fraction/percent.

Usually, a fraction is already a probability. Like if you roll a die, the probability that you will get a 1 is 1/6. So your probability would be your fraction.

Yes, the probability of an event is a number between 0 and 1 (both inclusive). You can write it as a fraction - in rational form or as a percentage.

No, because a probability must lie in the interval [0, 1].

No.

No. Probability values always have to be positive.

2 and 5 are both integers: their probability as a fraction is 0.

The probability is always a fraction except when it is 0 or 1. If a probability = 1 then it will definitely happen. If the probability is 0 then it will not happen. If you toss a fair coin the probability of heads is 1/2, and the probability of tails is 1/2. These fractions are representations of the probabilities. Not all fractions are representative of probabilities. Fractions can be used to represent a portion of a whole. Like what portion of a class is boys, and what portion is girls: If there are 8 boys and 7 girls, then the 8/15 of the class is boys, and 7/15 of the class is girls.

5/6 as a fraction

It is 1.

There is a chance that it might be.

Since 5/4 > 1, it cannot represent a probability of an event A, denoted by Pr(A), because for any event A, 0 ≤ Pr(A) ≤ 1. If A never occur, then Pr(A) = 0; if A always occur, then Pr(A) = 1.

Probability is a ratio of two counts: both of which MUST be positive. Their ratio cannot be negative.

An empirical estimate of the probability of an event is the ratio of the number of succesful outcomes to the total number of trials. By definition, the ratio is a fraction. However, there are many events for which the theoretical probability is related to irrational numbers. For example, it you randomly drop a pin on a floor of wooden boards, the probability that the pencil lies across a lateral join is related to pi. Being irrational, this cannot be expressed as a fraction.

Probability = number of times an event is expected to happen / number of opportunities for an event to happen It can be expressed as a percentage or a fraction.
