Answer #1

Let X is a random variable shows the number of students plan on pursuing a graduate degree out of 18. Here X has binomial distribution with parameters n=18 and p=0.42.

(a)

The probability that no more than five of the college graduates plan to pursue a graduate degree is

Excel function used : "=BINOMDIST(5,18,0.42,TRUE)"

(b)

The probability that exactly eight of the college graduates plan to pursue a graduate degree is

Excel function used : "=BINOMDIST(8,18,0.42,False)"

(c)

The probability that at least eight but no more than eleven of the college graduates plan to pursue a graduate degree is

Excel function used : "=BINOMDIST(11,18,0.42,TRUE)-BINOMDIST(7,18,0.42,TRUE)"
