1-If the records show that the probability of failing (with grade F) this course is p, [ use the answer of question 22 above as the probability, p, here], what is the probability that at most 2 students out of 16 fail this course? {Hint: use binomial distribution} (P=0.0625)

2-If the records show that the probability for a student to get a grade B this course is p, [ use the answer of question 19 above as the probability, p, here], what is the probability that exactly 4 students out of 16 will have a grade B for the course? {Hint: use binomial distribution} (p=0.1875)

3-What is the probability of selecting a grade A student for the first time either in 2nd or 3rd selection? {Hint: use geometric distribution with p value as the answer for question 18} (p=0.5625)
