Question 1

A diagram used to represent the outcomes of an experiment….

Answer 1

Tree Diagram

Question 2

If an event A can occur in r ways, and for each of these r ways, an event B can occur in s ways, then events A and B can occur, in succession, in r x s ways…is which property?

Answer 2

Fundamental Counting Property

Question 3

A diagram used to find probabilities of various events by weighting the branches of a tree diagram with appropriate probabilities….

Answer 3

Probability Tree Diagram

Question 4

Suppose that an experiment consists of a sequence of simpler experiments. Then the probability of the final outcome is equal to the product of the probabilities of the simpler experiments that make up the sequence ….is which property?

Answer 4

Multaplicative Property of Probability

Question 5

When drawing without replacement, the probabilities of the events can be viewed as those associated with the ends of the branches in a probability tree diagram by simply adding the events desired instead of using the Multiplicative Property of Probability….is which property

Answer 5

Additive Property of Probability

Question 6

List the four steps to finding the probability of a complex event…

Answer 6

1. ) Draw Probability Tree Diagram
2. ) Assign probabilities to each branch
3. ) Multiply the probabilities along individual branches to find the probability of outcome at the end of each branch
4. ) Add the probabilities of the relevant outcomes, depending on the event (Note: Upside Down U represents and, Upright U represents or; And means Multiply…Or means Add

Question 7

An array in which each entry is the sum of the two entries directly above it…..

Answer 7

Pascal’s Triangle
