Understanding Probability: Events Flashcard

Front

What are independent events in probability?

Back

Independent events are two or more events where the occurrence of one event does not affect the occurrence of the other. For example, rolling a die and flipping a coin are independent events.

What is the formula for the probability of the union of two mutually exclusive events?

Back

Front

If P(A) = 0.3 and P(B) = 0.7, and A and B are independent, what is P(A ∪ B)?

If P(A) = 0.2 and P(B) = 0.5, and A and B are mutually exclusive, what is P(A ∪ B)?

Front

What are mutually exclusive events?

Back

Mutually exclusive events are events that cannot occur at the same time. For example, when flipping a coin, getting heads and tails are mutually exclusive.

What is the probability of the intersection of two independent events A and B?

If P(A) = 0.6 and P(B) = 0.5, and A and B are independent, what is P(A ∪ B)?

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one event does not change the probability of the other event occurring.
