Experimental Probability of Compound Events

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or observations.

Front

How do you calculate experimental probability?

Back

To calculate experimental probability, use the formula: \( P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of trials}} \)
