Hello, I have a question regarding a homework problem."George is concurrently enrolled in both AP Statistics and AP Computer Science I. He has a quiz in both classes today. The probability that he makes an "A" on either his statistics quiz or his computer science quiz is 0.45 or 0.52, respectively. That probability that he makes an "A" on both quizzes today is 0.25. Are the events "making an "A" on the statistics exam" and "making an "A" on the computer science exam" independent? Explain by showing your work"

Hello, I have a question. What is the difference between mutually exclusive and independent? According to the book, they are supposed to be very different but I do not know how they are different.
