Introduction
*

In this unit of curriculum we will try to improve the students’ understanding of the elementary ideas included in probability theory. The unit will clearly define important words and ideas. Formulas for solving problems will be presented. Permutations, combinations, and compound probability will be discussed. Applications of the theory to practical problems will be demonstrated in the unit. Following the explanation of each topic a set of practice exercises will be given. There are several basic objectives for this unit of study. Upon completion of the unit, the student will be able to:

The material developed here may be taught as a complete unit in algebra 3 classes, or parts of it may be extracted and taught at the following levels of instruction: (1) in seventh or eighth grade mathematics classes; (2) in high school applied mathematics classes; (3) in first year algebra or second year algebra classes; (4) in adult basic education classes.

- understand and appreciate the use of probability in everyday life.
- solve problems involving permutations and combinations.
- define basic terms used in mathematical probability.
- compute the probability that a certain event will happen.
