In the joint probability table provided below we look at grades assigned (A,B,C,D or F) along with attendance being good or bad (G or B). Using this find the following probabilities: a. The probability that a randomly selected student earned an A. b. The probability that a randomly selected student earned an A and had good attendance. c. The probability that a randomly selected student earned an A or had good attendance. d. The probability that a student with good attendance earned an A. Are grades and attendance independent? Explain. You need not show work
