Chapter 4 Notes
Probability is defined as the likeliness of something happening. As a formula, consider P(x) = favorable outcomes ÷ possible outcomes

For compounded probability (more than one event): the probability of A and B is as follows P(A and B) = P(A) x P(B); the probability of A or B is P(A or B) = P(A) + P(B) - P(A)x P(B)
