Alison is the chair of a business department that consists of nine full-time faculty. She needs to schedule a meeting with each faculty to review their performance over the past year. The number of different ways these nine faculty can be scheduled is ------- .

The probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring.

The probability that Event A or Event B will occur refers to the union of Event A and Event B.

When two events are independent, the probability of them both occurring is simply the product of their individual probabilities of occurring.

-------are the number of different ways in which objects can be arranged without regard to order.

A frequency table indicates the number of occurrences of events that are classified according to two categorical variables.

Joint probability is another term used for simple probability.

---------- probability requires that you count the frequency that an event occurs through an experiment and calculate the probability from the experiment's relative frequency distribution.

A textbook sales representative is responsible for 25 schools and needs to choose three of these schools to work with today. The number of different ways he can schedule a time to call these schools is ------- .

Consider the following events: Event A = The survey respondent is a registered Republican. Event B = The survey respondent lives in Ohio. Events A and B are mutually exclusive.

When the order of objects is important, use permutations.

An event with a single outcome in its most basic form that cannot be simplified is known as a simple probability.

Which one of the following is not a valid number for a probability?

A psychology class consists of 14 business students and 21 non-business students. Sixteen students in this class are male. Eight students are both female and business majors. The number of men in the class who are not business majors is----- .

Two events are considered to be ----- if they cannot occur at the same time during the experiment.

------------ probability is used when we rely on experience and intuition to estimate the likelihood of an event.

If a customer at a particular grocery store uses coupons, there is a 50% probability that the customer will pay with a debit card. Thirty percent of customers use coupons and 35% of customers pay with debit cards. Given that a customer pays with a debit card, the probability that the same customer uses coupons is ------- .

You can conclude that, because events are not independent, they will be mutually exclusive.

According to a recent survey, 38% of U.S. households used only cell phones for their phone service. A random sample of four households was selected. The probability that the first three used only cell phones and the third had a landline is----- .

The probability of winning a 5/25 lottery game where 5 numbers are picked from a range of 25 is ---------.
