Probability Compound Events

What is the definition of dependent events in probability?

• Dependent events are events where the occurrence of one event affects the probability of the other event occurring.

• Dependent events are events that occur simultaneously without any influence on each other.

• Dependent events are events that are completely unrelated and do not affect each other's outcomes.

• Dependent events are events that always occur together regardless of other factors.

What does it mean for events to be mutually exclusive?

• They can occur at the same time.

• They are independent events.

• They cannot occur at the same time.

• They are always related.

How do you calculate the probability of two independent events occurring together?

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) * P(B)

• P(A and B) = P(A) - P(B)

• P(A and B) = P(A) / P(B)

How do you calculate the probability of two dependent events occurring together?

• P(A and B) = P(A) + P(B|A)

• P(A and B) = P(A) * P(B)

• P(A and B) = P(A) * P(B|A)

• P(A and B) = P(A) - P(B|A)

What is the definition of independent events in probability?

• Independent events are events where the occurrence of one event does not affect the probability of the other event occurring.

• Independent events are events that always occur together.

• Independent events are events that cannot happen at the same time.
