### Praxis Mathematics: Content Knowledge - Combinations and Permutations Objectives

The Praxis Mathematics: Content Knowledge test is used by certification bodies in many states to test prospective public high school teachers' proficiency in math prior to licensure. Certification candidates have two hours to complete the 50 multiple-choice questions on this test. Approximately six percent to eight percent of these questions will focus on discrete mathematics; this could include questions on combinations and permutations.

You can begin each lesson by taking a self-assessment quiz to see how much you remember about combinations and permutations from your postsecondary education. Next, watch the brief video, which will be led by a professional educator, to shore up your skills in this area. You can then take the quiz a second time to make sure you've absorbed the information presented in the video.
