Probability Countin

This math topic focuses on understanding and applying the principles of probability concerning combinations. It involves calculating the number of ways to select N cards from a group of M cards using factorial notation. The problems guide students in solving combination queries using formulas like \(\frac{n!}{r!(n-r)!}\), where \(n\) represents the total number of items, and \(r\) represents the number of items to choose. Each question requires expressing the solution as a factorial, reinforcing the student's familiarity with both combination concepts and factorial mathematical operations.
