Question 1

Random Variable

Answer 1

A variable whose values are determined by chance

Question 2

Discrete Probability Distribution

Answer 2

Consists of the values a random variable can assume and the corresponding probabilities of the values. The probabilities are determined theoretically or by observation.

Question 3

Theoretical probability distributions

Answer 3

You don’t have to perform the experiments to compute the probabilities.

Question 4

At least ____ trials

Answer 4

1-binomialcdf
The “X” is then one value less than # given.

Question 5

Fewer than _____ trials

Answer 5

Binomialcdf
Then “X” value is one less than # given

Question 6

Exactly _____ trials

Answer 6

Binomialpdf
All values are the same

Question 7

Expected Value

Answer 7

For a discrete random variable of a probability distribution is the theoretical average of the variable.

Question 8

If expected value of the game is 0

Answer 8

The game is considered fair

Question 9

If expected value of the game is positive

Answer 9

The game is in favor of the player

Question 10

If expected value of the game is negative

Answer 10

The game is in favor of the house

Question 11

Trial

Answer 11

Each repetition of the experiment

Question 12

Binomial experiment

Answer 12

A probability experiment that satisfies the following four requirements

Question 13

Binomial experiment requirements

Answer 13

1.) Must be a fixed # of trials.
2.) Each trial can only have 2 outcomes or outcomes that can be reduced to two outcomes.
3.) The outcomes must be independent of one another.
4.) Probability of success must remain the same for each trial.

Question 14

Binomial Distribution

Answer 14

The outcomes of a binomial experiment and the corresponding probabilities of these outcomes

Question 15

Outcomes are classified as

Answer 15

Successes or failures
