Question
1) At a college library exhibition of faculty publications, 3 math books, 4 social science books, and 3 bio books will be displayed on a shelf (assume that all books are different.)
In how many ways can the ten books be arranged on the shelf if books on the same subject matter are placed together?
(What I did)
For math: P(3,3)
For s.s: P(4,4)
For bio: P(3,3)
math and bio : P(3,3)=6
s.s: P(4,4)=24
I multiplied 6*6*24=864
