Topics in Permutations, Combination and Binomial Expansion

1

Fundamental Principles of Counting

  • Addition Principle: If there are m ways to do one task and n ways to do another task, then there are (m + n) ways to do either task
  • Multiplication Principle: If there are m ways to do one task and n ways to do another task, then there are (m × n) ways to do both tasks together
  • The word 'OR' indicates addition while 'AND' indicates multiplication
2

Factorial and Its Properties

  • Factorial n is denoted by n! and equals the product of all natural numbers from 1 to n
  • n! = n × (n-1) × (n-2) × ... × 3 × 2 × 1
  • By convention, 0! = 1 and 1! = 1
