1. Empirical probability

Empirical probability formula = Probability of an event happening is the ratio of the time similar events happened in the past.

or Empirical probability = Number of times event occurs/Total number of times experiment performed

2. Theoretical probability

To understand this, let us consider a random experiment.
Let A be an outcome of the random experiment. Then A is called an event.
The theoretical probability of the event A is given by
P(A) = Number of outcomes favourable to A / Total number of outcomes
Theoretical probability is also known as Classical probability or A Priori probability.
