General Multiplication Probability

The multiplication rule in statistics states that...

• to find the probability of two events happening at the same time, you can use the general multiplication rule formula of P(A ∩ B) = P(A) P(B)

• to find the probability of one event happening, you can use the general multiplication rule formula of P(A ∩ B) = P(A)

• to find the probability of two events happening at the same time, you can use the general multiplication rule formula of P(A ∩ B) = P(A) / P(B)

• to find the probability of two events happening at the same time, you can use the general multiplication rule formula of P(A ∩ B) = P(A)+ P(B)

Roll two 6-sided dice. Add the numbers together. Find the probability that one of the dice is a 6, given that the sum is greater than 9. The probability is _____. Write your answer as a fraction (do not simplify).

What is the General Multiplication Rule in probability?

• 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|A)

What is the multiplication rule for independent events?

• 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)

When are two events considered independent?

• When P(A and B) = P(A) + P(B)

• When P(A|B) = P(A) and P(B|A) = P(B)

• When P(A) = P(B)

• When P(A|B) = P(B) and P(B|A) = P(A)
