Catalog Data
Set concepts and operations, combinations, permutations, elementary probability theory including Bayes formula, linear systems of equations, matrix algebra, Gauss-Jordan row reduction, introduction to linear programming. This course does not count towards the major in mathematics. Prerequisite: Mathematics 107 or three years of college preparatory high school mathematics including geometry and Algebra II. Student must present satisfactory placement scores or obtain the permission of the Department of Mathematics.

Course Goals
Objectives: To introduce students to the fundamental concepts of set theory and probability theory and to develop the students' skills in expressing everyday situations in mathematical language, solving systems of linear equations by row reduction and setting up and solving linear programming models both geometrically and by the simplex method. Upon completion of the course, students should be able to:

• Use counting techniques and formulas to determine the number of elements in a set.
• Describe the sample space for an experiment; count the number of elements in the sample space; describe an event; count the number of elements in the event; compute the probability of the event.
• Find conditional probabilities; recognize when conditional probability is called for.
• Recognize independent events
• Use Bayes’ Formula to compute certain conditional probabilities.
• Use the Binomial model to compute certain probabilities.
• Sketch the graph of a line given its equation; write an equation of a line given information about the line; recognize parallel and intersecting lines.
• Solve systems of linear equations by row reduction; express systems in matrix representation; solve by matrix methods.
• Perform matrix algebra.
• Set up and solve application problems.
• Set up a linear programming model to solve a (LP) problem.
• Solve an LP problem graphically.
• Solve an LP problem algebraically (via the simplex method; and the two-phase OR the big-M method for problems which do not initially exhibit a feasible solution.

Exams
Three in-class examinations will be given. These will occur in approximately the fourth, seventh, and eleventh weeks. The precise date will be fixed and announced during class several days in advance of the day of the exam.

NOTE: If you miss an exam without an official excuse (such as illness or official university business), then you will be allowed to take a makeup exam, but with an automatic 25% deduction from the grade. To avoid this deduction, you must notify me with your official excuse before the date and time of the exam. This notification may be performed in person, via e-mail, or by telephone.

Final Exam
The final examination in the course will be comprehensive.  For information on date and time, check the Mathematics Department website later in the semester. Do not make plans to leave the university before the end of this week.  Travel plans do not constitute an official university excuse for missing an examination or for obtaining a conflict or makeup examination.  Hence, the above note regarding a 25% deduction will be enforced in the event that a student's travel plans conflict with the university's designated final examination period for this course.

Homework Homework will be assigned most days, and collected once a week. Selected problems will be graded. The lowest three scores will be dropped. No late homework will be accepted.

Quizzes Unannounced quizzes featuring problems similar to the homework problems will be given approximately once a week. The lowest three quiz scores will be dropped. No make-up quizzes will be given.

Attendance Attendance will be taken most days, and used to compute a good attendance bonus as follows. Less than 3 absences, the bonus is 3 points. After that each absence costs half a point, until you reach zero.

Grade Assignment It is a general practice in the mathematics department that in courses such as 139 with a common final, no student's course grade differ from his or her final exam grade by more than one letter.

Your Course Average will be computed with the following breakdown:
Homework 10%,
Quizzes 10%,
Each midterm is 16%,
And the final is 32%.

Then, your good attendance bonus, if appropriate, is added.
Then 90 is the lowest A, 80 the lowest B, 70 the lowest C, 60 the lowest D.

The grade you receive will be the one corresponding to your course average, unless this differs from your final exam score by more than one letter.
