Probability-1

Theoretical Probability is

• determined by carrying out a simulation or an experiment

• the expected probability

• how to find the answer

Experimental Probability is

• the expected probability

• how to find the answer

• determined by carrying out a simulation or an experiment

If the outcome of one event affects the other event

• concerts

• baseball games

• dependent events

• independent events

If the outcome of one event does not affect the other event

• independent

• dependent

• baseball games
