### AoPS Holidays

There are no classes May 29, July 4, or September 4.

### Who Should Take?

This course is appropriate for students in grades 6-9 who have mastered basic algebra up through solving linear equations and manipulating multi-variable expressions. Students who have completed our Introduction to Algebra A course should have sufficient background. This course is roughly the same difficulty as our Introduction to Number Theory class. For those preparing for contests, this course should help with MATHCOUNTS and the AMC 8/10/12 tests.

### Required Textbook

 Introduction to Counting & Probability By David Patrick A thorough introduction for students in grades 7-10 to counting and probability topics such as permutations, combinations, Pascal's triangle, geometric probability, basic combinatorial identities, the Binomial Theorem, and more.

I think this class was amazing. I thought probability would only be like, ‘I have 2 red balls and 2 green balls. What is the probability I pick a green ball?’ It is much more complex, deep, and entertaining. I enjoyed this class very much.
