If the outcomes of the trials are equally likely, then (and only then) is it the number of favourable outcomes and the total number of trials.

What is the probability ratio?
Probability is a measure of the likelihood of a given event and is a number in the range [0, 1]. That value, if expressed as a ratio, is a probability ratio. It can also be expressed as a percentage or a decimal fraction.
Is probability always a fraction?
Only when an event is probability to happen between a range of 1 to 0 then it is a fraction.
How do you turn probability into a fraction?
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.
What is the difference between a ratio and a prportion?
a ratio is a fraction of two numbers a proportion is = fractions
How can probability be expressed?
The probability of an event is a number in the interval [0, 1]. It can be expressed as a fraction or ratio or as a percentage. Furthermore, if the probability of an event is p, where 0<p<1, and if q = 1-p, then the probability of the event can also be expressed as odds of p to q in favour.

Why cant a negative fraction represent a probability?
Probability is a ratio of two counts: both of which MUST be positive. Their ratio cannot be negative.
Can a probability assume a negative value?
No. Probability is always represented as a positive ratio/fraction/percent.

Do you write a probability as a 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.
Probability can be defined as a between the number of successes and number of possible outcomes?
ratio
What is the difference between a ratio and a prportion?
a ratio is a fraction of two numbers a proportion is = fractions
Probability can be defined as a ratio between the number of and number of possible outcomes?
yes it can be defined more commonly as a ratio between the number of and numbr of possible outcomes
What is a relationship between two numbers that is expressed as a fraction?
It is a ratio
What is the formula for probability fraction?
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.
