Question

Leena is arranging 3 different books in a row on a shelf. Create a sample space for the arrangement of a detective story (D), a mystery story (M), and a comic book (C).

Answer 1

since we have 3 books in total, the possible arrangement for all three books is factorial 3 : \( 3\times2\times1 \) , which is equal to \(6\).

"Create a sample space"

we have to write down all possible arrangements -- that would be:

C M D
C D M
M C D
M D C
D M C
D C M

that is 6 options, which matches the factorial 3 -- so we are done.

Answer 2

3 *1* 2
3*2* 1
1* 3* 2
1 *2 *3
2 *1 *3
2*3 *1

Answer 3

hmm if youre referring to the arrangments, you are right, BUT its stated that: "detective story `(D)`, a mystery story `(M)`, and a comic book `(C)`."
