  1. Candidates for President: There are 99 candidates for the first position, which is president. After choosing the president, there are 88 candidates left for the position of secretary.
  2. Candidates for Secretary: Finally, for the treasurer position, there are 77 candidates left after choosing the president and secretary.
  3. Candidates for Treasurer: The total number of ways to choose the three officers is the product of the number of choices for each position.\newlineSo, we multiply 9×8×79 \times 8 \times 7 to get the total number of ways.
  4. Total Number of Ways: Calculating the product: 9×8×7=5049 \times 8 \times 7 = 504.
