The answer 0.12 represents "the portion of books in the library that are how-to books on electronics."

Here's the reasoning:

0.3 represents the portion of all books in the library that are how-to books.
0.4 represents the portion of how-to books that deal with electronics.

Thus, when you multiply 0.3 by 0.4, you are calculating the proportion of the total books in the library that are how-to books specifically about electronics, which is 0.12 (or 12% of the total books).
