SOLUTION

So we have detective story book represented as D

Mystery story book represented as M

And Comic book represented as C.

So, she can arrange it as follows

D C M

C D M

M C D

C M D

M D C and

D M C

So, the sample space is 6 ways

Or you can say


3!=3*2*1=6ways.

Therefore, the answer is 6 ways
