The grade scored by Mehmet in a course is normally distributed with a mean of 50 and standard deviation of 4. a) If the probability that Mehmet will pass from this course is 0.8413, what is the passing grade? (Note that to pass from a score, a student should score a grade which is higher than the passing grade.) b) The grade scored by another student from the same course is again normally distributed with a mean of 56 and standard deviation of 3. Find the probability that this student will score higher grade than Mehmet.
