Full solution

Q. There were 1313 students running in a race. How many different arrangements of first, second, and third place are possible?\newlineAnswer:
  1. Choose First-Place Winner: Determine the number of ways to choose the first-place winner.\newlineSince there are 1313 students running in the race, any one of the 1313 can come in first place.\newlineCalculation: There are 1313 choices for the first place.
  2. Choose Second-Place Winner: Determine the number of ways to choose the second-place winner.\newlineAfter the first place has been chosen, there are 1212 students left who can come in second place.\newlineCalculation: There are 1212 choices for the second place.
  3. Choose Third-Place Winner: Determine the number of ways to choose the third-place winner.\newlineAfter the first and second places have been chosen, there are 1111 students left who can come in third place.\newlineCalculation: There are 1111 choices for the third place.
  4. Calculate Total Arrangements: Calculate the total number of different arrangements for the first three places.\newlineTo find the total number of different arrangements, we multiply the number of choices for each position.\newlineCalculation: 1313 choices for first place ×12\times 12 choices for second place ×11\times 11 choices for third place =1716= 1716 different arrangements.
