General Multiplication Rule Probabilities

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

• 0.1

• 1.1

• 0.9

• 0.3

Explain the components of a probability model and how it is used to calculate probabilities.

• The components of a probability model include the sample space, events, and probabilities assigned to each event. It is used to calculate probabilities by using the rules of probability, such as the addition rule and multiplication rule.

• The components of a probability model include the alphabet, numbers, and colors. It is used to calculate probabilities by flipping a coin.

• The components of a probability model include the weather, sports, and politics. It is used to calculate probabilities by guessing.

• The components of a probability model include the population, GDP, and unemployment rate. It is used to calculate probabilities by using astrology.

What is the Multiplication Rule?

• P(A) ⋅ P(B|A)

• P(A) - P(B)

• P(A) ⋅ P(B)

• P(A) + P(B) - P(A ∩ B)

What is the Multiplication Rule?

• P(A) ⋅ P(B|A)

• P(A) - P(B)

• P(A) ⋅ P(B)

• P(A) + P(B) - P(A ∩ B)

The sum of the probabilities of all the outcomes must equal 1. Every probability model MUST obey this rule.

• True

• False

The spinner below is divided into 4 equal parts. It is spun once, and the coin is flipped once. What is the probability of obtaining red on the spinner followed by heads on the coin?
