AP Stats Probability

What is a sample space in a probability model?

• A list of impossible outcomes

• A list of all possible outcomes

• A list of probable outcomes

• A list of certain outcomes

What does the notation S={....} represent in probability?

• A set of impossible events

• A sample space

• A single outcome

• A random variable

What is the range for probability values?

• 0-100%

• 0-50%

• 0-200%

• 0-10%

What is the probability that all outcomes will occur?

• P(S)=1

• P(S)=0

• P(S)=0.5

• P(S)=2

If two events are disjoint, what is the probability of their intersection?

• The empty set

• 1

• 0.5

• 2

What is the formula for the General Addition Rule in probability?

• P(A or B) = P(A) + P(B) - P(A and B)

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) - P(B)

• P(A or B) = P(A) * P(B)

What is a Venn Diagram used for in probability?

• To calculate the exact probability of a single event

• To organize the likelihood of two separate events that overlap

• To determine the probability of independent events

• To find the mean of a data set

What is the formula for Conditional Probability?

• P(A|B) = P(A) + P(B)

• P(A|B) = P(A) * P(B)

• P(A|B) = (P(A and B)) / P(B)

• P(A|B) = P(B) / P(A)

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 purpose of tree diagrams in probability?

• To calculate the mean of a data set

• To organize circumstances and outcomes in conditional probability

• To determine the mode of a data set

• To find the median of a data set
