A probability estimated by doing an experiment many times

Probability based on repeatedly performing an experiment, estimating the probability each time.

Probability determined using knowledge about the situation to calculate the probability

The probability that one event occurs under the condition that another event occurs

$$\frac{The\ number\ of\ times\ an\ event\ occurs}{the\ total\ number\ of\ events\ that\ occured}$$

$$\frac{the\ total\ number\ of\ events\ that\ occured}{the\ number\ of\ times\ an\ event\ occurs}$$
