The rule of addition and the rule of multiplication are two important rules of probability that describe how probabilities are calculated for multiple events.

Sep 25, 2025 · These fundamental principles, including the addition, multiplication, and complement rules, are used to calculate the likelihood of events occurring and help in determining the …

The multiplication rule and the addition rule are used for computing the probability of A and B, as well as the probability of A or B for two given events A, B defined on the sample space.

Key Point 5 The Addition Law of Probability - Simple Case If two events A and B are mutually exclusive then P(A ∪ B) = P(A) + P(B)

How to use three probability laws (the rules of addition, subtraction, and multiplication) to solve probability problems. Includes problems with solutions.

I deal three cards in succession from a shuffled deck. What's the probability that the first card is the queen of spades, the second is the six of diamonds, and the third is a queen?

Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. P (A or B) = P (A) + P (B) Let’s use this addition rule to …
