This is how Edward’s Lotteries work. First, 9 different numbers are selected. Tickets with exactly 6 of the 9 numbers randomly selected are printed such that no two tickets have the same set of numbers. Finally, the winning ticket is the one containing the 6 numbers drawn from the 9 randomly. There is exactly one winning ticket in the lottery system. How many tickets can the lottery system print? (A) \(9P_6\) (B) \(9P_3\) (C) \(9C_9\) (D) \(9C_6\) (E) \(6^9\)

Can someone explain this? I thought it would be 9P6 since it states that "Tickets with exactly 6 of the 9 numbers randomly selected are printed such that no two tickets have the same set of numbers.

(E) \(6^9\) 9 numbers, choose 6 of them. 9C6. D. Selected exactly 6 of the 9 available numbers means they're randomly picking 6 of the 9 numbers. The part that lets you know that it's indeed a choose function and not permutation is that the problem says that "no two tickets contain the same numbers" and (paraphrasing) "the winning ticket contains the 6 winning numbers" So order doesn't matter. Does that help?
