Number of trials is how many times you test your hypothesis. When you are doing trials the end result may come out differently every time.
The relative frequency of an event, from repeated trials, is the number of times the event occurs as a proportion of the total number of trials - provided that the trials are independent.
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.
The probability that is based on repeated trials of an experiment is called empirical or experimental probability. It is calculated by dividing the number of favorable outcomes by the total number of trials conducted. As more trials are performed, the empirical probability tends to converge to the theoretical probability.
the ratio of the number favorable outcomes to the total number of trials.
