With probability ratios the value you get to describe the strength of the relationship when you compare (A given B) to (A given not B) is not the same as what you get when you compare (not A given B) to (not A given not B). This is, IMHO, a big problem. There is no such problem with odds ratios.

What type of probability is when it uses sample spaces to determine the numerical probalitiy that an event will happen?

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.
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.
What probability is the ratio of favorable outcomes to possible outcomes?
It is the theoretical probability of the event.
How are ratio and probability the same?
A ratio is a comparison of the relative size of two different things. Probability is the change that something will (or will not) occur. Probability can be expressed as a ratio of Yes to No (or, "will occur" to "won't occur"). That is, Probability is the relative size of Yes to No. So, if something is said to have a 60% Probability of occurring, what that is indicating is that, out of 100 tries, 60 will be the outcome indicated. While probability is usually expressed as a percentage, it is entirely possible to express it as a ratio. In the aforementioned example, a 60% Probability of occurrence could also be said to be a 60:40 (or, reduced, 3:2) ratio in favor of happening.

Can a probability assume a negative value?
No. Probability is always represented as a positive ratio/fraction/percent.
What do you use to calculate probability?
Probability is the ratio of the count of anticipated outcomes divided by the count of all outcomes.
What is the first number in a probability ratio?
The number of "favourable" outcomes.
What is odds ratio?
A crude odds ratio is the probability that a case preceeded the control in regard to exposure and history.
What type of probability uses a knowledge of sample spaces as opposed to experiments to determine the numerical probability that an event will occur?
Theoretical probability.
What is another name for Experimental Probability?
Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.
