Compare sums of unit fractions

What you'll learn

  • Identify and differentiate between permutation and combination problems by analyzing word problems and correctly classifying at least 8 out of 10 examples.
  • Apply the permutation formula (nPr = n!/(n-r)!) to solve at least 7 out of 10 problems involving arrangements where order matters, showing all steps in the calculation.
  • Apply the combination formula (nCr = n!/(r!(n-r)!)) to solve at least 7 out of 10 problems involving selections where order does not matter, showing all steps in the calculation.
  • Solve complex counting problems involving both permutations and combinations by breaking them down into smaller, manageable steps and correctly applying the appropriate formulas in at least 3 out of 5 multi-step problems.
