How many sets of 5 books can be selected from 12 different books?
12!/(5!*7!)The number of ways to arrange nitems is n!, where "!" is the factorial function. The number of ways we can arrange the 12 books is therefore 12!. However, we don't really care what order the first 5 books are in, or what order the last 7 books are in, as long as they're the same books. We therefore divide by the number of ways to arrange 5 books and the number of ways to arrange 7 books.

If John plans to donate his collection of 3042 books to three libraries in the ratio of 135 How many books will each library get?
Total number of books=3042 Sum of the terms of the ratio=1+3+5=9 Number of books to the first library=1/9*3042 =338 Number of books to the second library=3/9*3042=1014 Number of books to the third library=5/9*3042=15210 Hence, the first library will get 338, the second library will get 1014 and the third library will get 15210 books.
How many ways can you arrange the numbers 1468?
There are 4 digits. You can pick one of them as the first digit. So you can pick the first number 4 ways. Having picked the first number, the second number you can pick in only 3 ways. Having picked the first number and the second number you can pick the third number in only 2 ways. Having picked the first number and the second number and the third number you can pick the fourth number in only 1 way. So total ways of arranging 1468 would be 4 x 3 x 2 x 1 = 24
