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.

Was the outcome of getting heads or tails in the 20 tosses same as the probability ratio?
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
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.
What probability is the ratio of favorable outcomes to possible outcomes?
It is the theoretical probability of the event.
What is the probability of getting male and female offsring in human?
The global gender probability, at birth, is approx 0.517 for male and 0.483 for female. This is not the same as the gender ratio at conception because of gender-specific abortion.
What is the first number in a probability ratio?
The number of "favourable" outcomes.
