Suppose at a small college, 30% of the students are freshmen, and 60% of the students live on campus. Also, assume that living on campus is independent of the class of the student.

d. If three random students are selected, what is the probability that all three students live on campus? I don't know how to start. Thank you for you help in advance.

Answer #1

P[ Student live on the Campus ] = 60% = 0.60

Since the living on campus is independent of the class of the student

The probability will remain same in each selection of student

P[ probability that all three students live on campus ] = P[ Student live on the Campus ]*P[ Student live on the Campus ]*P[ Student live on the Campus ]

P[ probability that all three students live on campus ] = 0.6*0.6*0.6

P[ probability that all three students live on campus ] = 0.216

The administration at your college announces that, on average, commuting students live farther than 30 miles from campus. The announcement came as somewhat of a surprise and took place at a press conference where it was important to make the point that the college attracts students who live 'far' from campus. A student advocacy group takes a random sample of 9 commuting students and records how far, in miles, they live from campus: 19,22,25,28,30,35,40,46,50. a. Write a set of appropriate...
