Exam 4: Introduction to Probability

An experiment consists of selecting a student body president and vice president.All undergraduate students (freshmen through seniors) are eligible for these offices.How many sample points (possible outcomes as to the classifications) exist?

When the results of experimentation or historical data are used to assign probability values, the method used to assign probabilities is referred to as the

The symbol ∩ shows the

Some of the CDs produced by a manufacturer are defective.From the production line, 5 CDs are selected and inspected.How many sample points exist in this experiment?

From a group of six people, two individuals are to be selected at random.How many selections are possible?

Of the last 100 customers entering a computer shop, 25 have purchased a computer.If the classical method for computing probability is used, the probability that the next customer will purchase a computer is

Events A and B are mutually exclusive.Which of the following statements is also true?

If A and B are mutually exclusive, then​

The counting rule that is used for counting the number of experimental outcomes when n objects are selected from a set of N objects where order of selection is not important is called the

Events that have no sample points in common are

If A and B are independent events with P(A) = 0.38 and P(B) = 0.55, then P(A | B) =

Bayes' theorem is used to compute

Six applications for admission to a local university are checked, and it is determined whether each applicant is male or female.How many sample points exist in the above experiment?

​A collection of sample points is

If P(A) = 0.48, P(A ∪ B) = 0.82, and P(B) = 0.54, then P(A ∩ B) =

Posterior probabilities are​​

A method of assigning probabilities based upon judgment is referred to as the

A method of assigning probabilities based on historical data is called the

Two events are mutually exclusive

Each individual outcome of an experiment is called
