The correct Answer is:
To solve the problem of arranging 6 players to throw a cricket ball such that the oldest player does not throw first, we can follow these steps: ### Step 1: Identify the players Let's denote the players as P1, P2, P3, P4, P5, and P6, where P6 is the oldest player. ### Step 2: Determine the first thrower Since the oldest player (P6) cannot throw first, we have 5 options for the first thrower. The possible players for the first throw are P1, P2, P3, P4, and P5. ### Step 3: Arrange the remaining players After choosing the first thrower, we have 5 players left (including P6) to arrange in the remaining 5 positions. The number of ways to arrange these 5 players is given by the factorial of the number of players, which is 5!. ### Step 4: Calculate the total arrangements The total number of arrangements can be calculated as follows: - For the first throw, we have 5 choices (P1, P2, P3, P4, P5). - For the remaining 5 players, we can arrange them in 5! ways. Thus, the total number of arrangements is: \[ \text{Total arrangements} = 5 \times 5! \] ### Step 5: Calculate 5! Calculating 5!: \[ 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120 \] ### Step 6: Calculate the final answer Now substituting back into the total arrangements: \[ \text{Total arrangements} = 5 \times 120 = 600 \] ### Conclusion Therefore, the number of ways of arranging the 6 players so that the oldest player does not throw first is **600**. ---
