Frequently Asked Questions
What is the difference between theoretical and experimental probability?
Theoretical probability is calculated using mathematical reasoning, while experimental probability is based on actual observations or experiments.
How do you find the probability of independent events?
For independent events, the probability of both occurring is the product of their individual probabilities: P(A and B) = P(A) x P(B).
