Ashley conducted an experiment to see which one of her friends has the best sense of smell. She bought 15 scratch-and-sniff stickers, 11 of which smelled like oranges. If after the first day of the smell tests, Ashley’s friends had randomly scratched and sniffed 12 stickers, what is the probability that exactly 9 of the chosen stickers smelled like oranges?
