Outcomes

In this lesson you will

• apply knowledge of combinations and permutations in a variety of contexts

Students will be expected to:

• determine probabilities using permutations and combinations
• develop and apply formulae to evaluate permutations and combinations

Introduction

Mathematical Modeling, Book 3    p.336 - 339

In this section you will discover that some probabilities are easily counted using permutations and combinations.  The section emphasizes that combinations and permutations are just specialized techniques for counting. This counting is important because the calculation of probabilities involves determining the quotient of two counted values: the number of favourable outcomes and the number of total outcomes.

This section should take you between 1 and 1.5 hours to complete.

Prerequisites

To be successful in this lesson, it would be helpful to know the following:

• permutations
• combinations
• Multiplication Principle
• Probability calculations
