type of book	number
literature	25
childrens	4
nonfiction	11

which explains whether or not sahiras sample is representative?
no, it is not representative because literature books were chosen much more often than the other types.
yes, it is representative because each type of book was chosen a unique number of times.

yes, it is representative because each type of book was selected as part of the sample.

Explanation:

A representative sample should reflect the proportion of different types in the population. Here, literature books are chosen much more often than others, which means the sample doesn't accurately represent the library's book - type distribution.

Answer:

No, it is not representative because literature books were chosen much more often than the other types.
