5.2 Reading Quiz - Probability Rules

A (a)   model is a description of some random process that consists of two parts: a list of all possible outcomes and the probability for each outcome.

The list of all (a)   outcomes is called the sample space.

An __________ is any collection of outcomes from some random process.

• imitation

• response

• outcome

• event

If all the outcomes are equally likely, how is probability of an event calculated?

• # of outcomes in the event divided by the total # of outcomes

• # of outcomes in the event# of outcomes in the event multiplied by the total # of outcomes

• the total # of outcomes divided by the # of outcomes in the event

• the total # of outcomes multiplied by the # of outcomes in the event

Select all of statements below that are true:

• The compliment rule is P(A^c)= 1 - P(A)

Two events A and B are (a)   if they have no outcomes in common and so can never occur together.

The addition rule for mutually exclusive events A and B says that

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) - P(B)

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) - P(B)
