Aschool librarian ordered new books for the library. 1/3 are science 2/5 are biography and the rest of the books are fiction. what fraction of the books ordered are fiction?

i think it would be 4/15 because science is 6/15 and fiction is 5/15

i don't need it but brainliest is appreciated

The way I would do this problem would be to find a common denominator for both of the fractions.

5/15

6/15

And then we can find out how many books there are left.

5/15 + 6/15 is 11/15

11/15 books are about science and biography, the other 4/15 are fiction.

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
