You can use Appendix Table E or Excel Function Binomdist.

About 30% of adults in United States have college degree.

(probability that person has college degree is p = 0.30).

If N adults are randomly selected, find probabilities that

1) exactly X out of selected N adults have college degree

2) less than X out of selected N adults have college degree

3) greater than X out of selected N adults have college degree

Choose your numbers for N and X (portion of N).

(Probability that person has college degree is p = 0.30).

If n adults are randomly selected, find probabilities that:

1) Exactly 24 out of selected 50 adults have college degree

=BINOMDIST(24,50,.30,FALSE) = .0032

2) Less than 36 out of selected 75 adults have college degree

=BINOMDIST(35,75,.03,TRUE) = .9992

3) Greater than 22 out of selected 62 adults have college degree

=1-BINOMDIST(23,62,.03,TRUE) = .0893
