The results of a calculus exam are normally distributed with a mean of 76 and a standard deviation of 6. You plan to randomly select one of the learners taking the course. What is the probability you randomly select a learner that scored above an 80 on their exam? What is the probability you randomly select a learner that scored between a 66 and 90 on their exam? Given that a passing score is 60 and higher, what is the probability you randomly select a learner that failed the exam?
