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 experiments.

What does the fundamental counting principle state?

Back

The fundamental counting principle states that if one event can occur in 'm' ways and a second event can occur independently in 'n' ways, then the two events can occur in m × n ways.

Front

What is theoretical probability?

Back

Theoretical probability is the probability of an event based on the possible outcomes in a perfect world, calculated using the formula: (Number of favorable outcomes) / (Total number of outcomes).
