LOS e: Define and explain the multiplication, addition, and total probability rules.

 

 

 

The multiplication rule of probability is used to calculate the:

A) probability of at least one of two events.

B) unconditional probability of an event, given conditional probabilities.

C) joint probability of two events.

The multiplication rule of probability is used to calculate the:

A) probability of at least one of two events.

B) unconditional probability of an event, given conditional probabilities.

C) joint probability of two events.

The multiplication rule of probability is stated as: P(AB) = P(A|B) × P(B), where P(AB) is the joint probability of events A and B.

The unconditional probability of an event, given conditional probabilities, is determined by using the:

A) addition rule of probability.

B) multiplication rule of probability.

C) total probability rule.

The unconditional probability of an event, given conditional probabilities, is determined by using the:

A) addition rule of probability.

B) multiplication rule of probability.

C) total probability rule.

---

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|B_n)P(B_n)
