Probability

Question 1

Independent Events Formula

Answer 1

P(A ∩ B) = P(A) * P(B)

Question 2

Dependent Events Formula

Answer 2

P(A ∩ B) = P(A|B) * P(B)

Question 3

Conditional Probability Formula

Answer 3

P(A|B) = P(A ∩ B) / P(B)

Question 4

Overlapping Events Formula

Answer 4

P(A U B) = P(A) + P(B) - P(A ∩ B)

Question 5

Mutually Exclusive Formula

Answer 5

P(A U B) = P(A) + P(B)

Question 6

Are mutually exclusive events independent or dependent?

Answer 6

Always dependent

Question 7

How do you know if two events are dependent on each other?

Answer 7

If P(A ∩ B) = P(A) * P(B)
