Session 2: Quantitative Methods: Basic Concepts
Reading 8: Probability Concepts
LOS e: Define and explain the multiplication, addition, and total probability rules
The unconditional probability of an event, given conditional probabilities, is determined by using the:
|
A) |
addition rule of probability. | |
|
B) |
total probability rule. | |
|
C) |
multiplication rule of probability. | |
The total probability rule us used to calculate the unconditional probability of an event from the conditional probabilities of the event given a mutually exclusive and exhaustive set of outcomes. The rule is expressed as:
P(A) = P(A|B1)P(B1) + P(A|B2)P(B2) + ... + P(A|Bn)P(Bn)
