Now that we know about permutations and combinations, we can finally solve probability problems. The fourth installment of a 21-part module has future mathematicians analyzing word problems to determine whether permutations or...

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

Count the benefits of using the resource. The second installment of a 21-part module focuses on the fundamental counting principle to determine the number of outcomes in a sample space. It formalizes concepts of permutations and...

Have a blast with Sal as he solves these SAT practice questions! He enjoys himself with visualization and combination problems, showing not only how to solve the problems but to see math as a riddle rather than a threat.

A geometry video explains how to solve for midpoint, length of a line, and use the Pythagorean Theorem. It includes multiple guided practice problems for all three equations.

Upper level math doesn't have to be unapproachable. An instructional video uses virtual manipulatives to demonstrate the meaning of a permutation, a combination, and factorial.    

How many different ways can five people be arranged in any order in three chairs? Sal shows how combinations are different than permutations. He derives the formula for finding the combination without repetition.

Students will solve discrete math problems involving permutations, factorials, and combinations. Students are responsible for deciding which is appropriate to solve a given word problem.

The notion of permutations is used when rearranging objects or values. How many ways can the letters in the word NUMBER be rearranged? Don't try writing them all out one by one because it would take a long time. Use the Fundamental...

This MathWorld site is a lite to link to a multitude of sites involving permutations. Look through to find your specific needs. If you are looking at this site with regards to a probability and statisics class you will probably want to...
