On an island where knaves never tell the truth and knights always tell the truth, you meet 3 of the island's inhabitants: fred, george, and quincy. you ask fred, "are you a knave? " fred says the answer to the other natives, but you can't hear him. george turns to you and says that fred denied being a knave. quincy says fred is a knave. how many of the three are knaves?

There is one knave

Step-by-step explanation:

Let's analyze the two possible scenarios, from the unheard Fred's answer

- SCENARIO 1: Fred is a knave.

If Fred is a Knave, he must have told to the other natives that he wasn't, remember that Knaves will never tell the truth. In that sense, George said that Fred denied being a knave, he would be telling the truth (Fred is a knight) and Quincy said that Fred is a knave, which would also be true (Quincy is a knight too).

-SCENARIO 2: Fred is a knight

If Fred is a knight, he must have told to the other natives that he wasn't a knave, he would be telling the truth. In this case, George would also be telling the truth by ensuring that Fred denied being a knave (Fred is a knight). However, Quincy would be lying to ensure that Fred is a knave. In this scenario Quincy is the knave

In conclusion, in both scenarios, there is only one knave.
