This week we practice with Binomial Distribution.
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).

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 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
=1BINOMDIST(23,62,.03,TRUE) = .0893posted by Anonymous
