Define a compound event. Outline the difference between finding the probability of one event AND another and one event OR another. The AND another involves finding P(event A & event B) while OR involves finding P(event A) + P (event B). P is the probability. A few problem examples will be given and the answers evaluated. Finding the Probability when 2 events are mutually exclusive will be discussed with the formula given as P(A) + P(B) - P(A+B). A few examples of this type will be given.
