A tournament is assigning player numbers to participants, where each number is different. Which situation best illustrates this?

• Forming a debate team from a class

• Assigning unique player numbers in a tournament

• Choosing two subjects to study for an exam

• Selecting 3 students to represent the school in a competition

A student is calculating P(6,6), which represents the number of ways to arrange all 6 objects in a row. Why does this simplify to 6!?

• Because P(6,6) is equivalent to 6! / (6−6)! and 0! = 1.

• Because arranging 6 objects in a row always gives a value of 1.

• Because 6! is always equal to 6 multiplied by itself.

• Because P(6,6) is undefined when n = 0.
