In a competition, first, second, and third prizes are awarded among 9 participants. No participant can receive more than one prize. How many outcomes are possible?

Answer and explanation

Correct answer: 504 outcomes

The prizes are distinct, so order matters. There are 9 choices for first prize, 8 remaining choices for second, and 7 for third. Hence, the number of outcomes is 9 × 8 × 7 = 504.
