Kyoko has a deck of 30 cards, numbered 1 through 30. She draws a card and then returns it to the deck. She does this 8 times. What is the probability that she doesn't draw the same card more than once?

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
