What is the Addition Rule of Probability?

Back

The Addition Rule of Probability states that the probability of the occurrence of at least one of two events A or B is given by P(A ∪ B) = P(A) + P(B) - P(A ∩ B).

Define mutually exclusive events.

Back

Mutually exclusive events are events that cannot occur at the same time. If A and B are mutually exclusive, then P(A ∩ B) = 0.

Define independent events in probability.

Back

Independent events are events where the occurrence of one event does not affect the occurrence of another. For independent events A and B, P(A ∩ B) = P(A) * P(B).

What is the probability of drawing a heart or a queen from a standard deck of cards?

Back

P(Heart) + P(Queen) - P(Heart ∩ Queen) = 13/52 + 4/52 - 1/52 = 16/52.
