QI/ Four engineering classes A, B, C and, D were tested for the percentage of students success in the examination of statistics Engineering measured from each one of them. The following table gives the number of students in each class and percentage of students success collected from each class. Compute the followings: Class D Number of students in each class 25 30 25 20 Percentages of student's success in each class 64% 68% 75% 72% 1-Total percentage of observed failed students? 2- If a certain class is tested randomly, compute the probability that it is success taken from class A and D?
