Exchanging groups of coins

What you'll learn

• Calculate the number of permutations of 'n' distinct objects taken 'r' at a time, using the permutation formula (nPr = n!/(n-r)!), with at least 80% accuracy on a worksheet containing 10 problems.
• Distinguish between permutation and combination problems by correctly identifying at least 4 out of 5 word problems as either a permutation or a combination scenario, justifying the choice based on whether order matters.
• Solve real-world problems involving permutations, such as arranging books on a shelf or determining the number of possible batting orders, by applying the permutation formula and showing all steps in the solution process, achieving a correct answer on at least 3 out of 4 application problems.
• Explain the difference between permutations with and without repetition using clear and concise language, providing at least two distinct examples of each, as demonstrated in a short written response.
