This is how Edward’s Lotteries work. First, 8 different numbers are selected. Tickets with exactly 6 of the 8 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 8 randomly. There is exactly one winning ticket in the lottery system. How many tickets can the lottery system print?
Pick one
A) 8P6
B) 8P3
C) 9C9
D) 8C6
E) 69
since we have to select random 6 numbers from 8 and they all are distinct. i think it should be 8C6 or 8C6.
