There are 3 literature books, 4 geography books, and 3 science books on a shelf. If 3 books are chosen at random one after the other, what is the probability that a literature book, a geography book, and a science book are selected if replacement does not take place?

(3/10)*(4/9)*3/8) The denominator decreases by 1 each time because there is 1 less book, now just multiply all that together
