\n" ); document.write( "I think saying the statement of the problem is incorrect is a bit harsh. I do think that the problem is presented poorly.

\n" ); document.write( "By implication, the problem really asks the probability if, WHEN 9 BOOKS ARE SELECTED FROM 9 science books and 10 math books, 4 science books and 5 math books are selected.

\n" ); document.write( "P(4 science and 5 math) = \"%28C%289%2C4%29%2AC%2810%2C5%29%29%2FC%2819%2C9%29+=+%28126%2A252%29%2F92378+=+31752%2F82378\"

\n" ); document.write( "Of course simplify the fraction or express as a decimal if needed.
