  1. Understand the problem: Understand the problem.\newlineWe need to determine the number of different ways to award three distinct prizes to twenty-eight people. This is a permutation problem because the order in which the prizes are awarded matters.
  2. Set up the permutation formula: Set up the permutation formula.\newlineThe number of ways to award the prizes is the number of permutations of 2828 people taken 33 at a time, which is denoted as P(28,3)P(28, 3).
  3. Calculate the permutation: Calculate the permutation. \newlineP(28,3)P(28, 3) is calculated as 28!(283)!\frac{28!}{(28-3)!}, where !"!" denotes factorial, the product of all positive integers up to that number.
  4. Perform the calculation: Perform the calculation.\newline28!/(283)!=28!/25!=28×27×26×25!/25!28! / (28-3)! = 28! / 25! = 28 \times 27 \times 26 \times 25! / 25! (since the factorials cancel out)\newline=28×27×26= 28 \times 27 \times 26\newline=19656= 19656
  5. Conclude with the final answer: Conclude with the final answer.\newlineThere are 1965619656 different ways in which the prizes can be awarded.
