Question 7 of 10 Find the probability of selecting 5 science books and 4 math books from 13 science books and 10 math books. The books are selected at random. Use a graphing calculator and round the answer to six decimal places. P(5 science and 4 math) = [ ]

Solution

number of ways of selecting 5 science books and 4 math books from 13 science books and 10 math books

= 13C5 * 10C4

= 270270

total number of ways of selecting any book = 23C9 = 817190

required probability = 270270/817190 = 0.330731
