What is the probability that a student is taking more than 3 classes? 0.44✓ d.) What is the probability that a student is taking less than 2 classes? 0.17 ✔ e.) What is the probability that a student is taking no more than 2 clases? 0.45 f.) What is the average (mean) amount of classes a student takes at BHCC? 2.92 g.) What is the standard deviation for the amount of classes a student takes at BHCC? (round to two decimal places)
