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)

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.
