The general multiplication rule. For any two events, we can say that. P ( A and B) = P ( A) ⋅ P ( B | A) ‍. The vertical bar in P ( B A) ‍ means "given," so this could also be read as "the probability that B occurs given that A has occurred." The theoretical probability of an event is calculated based on information about the rules and circumstances that produce the event. It reflects the number of times an event is expected to occur relative to the number of times it could possibly occur.

Exercise 5.E. 8: Probability. In a town of 10,000 people, 400 have beards (all men), 4000 are adult men, and 5 of the townspeople are murderers. All 5 murderers are men and 4 of the murderers have beards. Suppose you go to this town and select a towns person at random. Let A be the event that the person turns out to be one of the five …The probability that you will draw a green or a red marble is \ (\frac {5 + 15} {5+15+16+20}\). We can also solve this problem by thinking in terms of probability by complement. We know that the marble we draw must be blue, red, green, or yellow. In other words, there is a probability of 1 that we will draw a blue, red, green, or yellow marble.
