Trevor just received a jar of mixed nuts containing 325 almonds, 250 pistachios, 75 cashews, and 350 pecans for his birthday. He's going to start randomly choosing some nuts from the jar, and he's not going to do anything that would favor him choosing any particular type of nut over another. If Trevor chooses a pistachio and then eats it, what is the probability that the second nut Trevor chooses is also a pistachio?
