There is a 40% chance that a student at M University is a
liberal arts student (the university has either arts or science
majors). Three students are chosen at random. Let random variable X
be the number of students out of the three who are studying
arts.
(a) Does this experiment have five binomial characteristics?
Explain. If it does, find the value of n and p.
(b) FindP(X=0),P(1?X<3),P(X?2)
