# PCMI Problem sets and Binomial Expansion

PCMI has problem sets on probability and combinatorics. Most of the material is contained in their “Probability through Algebra” course.

Some highlights:

• Each problem set contains a “Game of the Day” with problems surrounding game shows.
• They build binomial expansion (i.e. $(x + 2y)^7$) on top of binomial probability. See page 2 of this document:
