Roughly 1 in 6 students enrolled in higher education took at least one online course last fall. Choose 4 enrolled students at random. Find the probability none of the 4 took a course online.
Homework Answers
Answer #1
Roughly 1 in 6 students enrolled in higher education took at least one online course last fall.
So, the chance that a randomly selected student, enrolled in higher education, took at least one online course, is 1/6.
So, the chance of not taking a online course, is 5/6.
Now, we choose 4 enrolled students in random.
We have to find the probability that none of the 4 took a course online.
Now, each will have probability of not taking a course, 5/6.
So, the required probability is
So, the probability that none of the 4 students took a course online, is 0.4822.

All first-year students at a university are enrolled in 1 of 30
sections of seminar course (40 students per section). To choose a
sample of first year students from this university, a researcher
begins by randomly selecting 5 sections from the seminar course,
followed by randomly selecting 15 students within each of the 5
sections. This would be an example of:

a. Systematic random sampling
b. Convenience sampling
c. Simple random sampling
d. Stratified sampling

6. Students in one statistics course need to earn a grade of at
least C, otherwise they need to repeat the course. It is also known
that 85% of all students who attend class regularly will earn a
grade of at least C, while only 30% of those students who do not
attend class regularly will earn a grade of at least C.
Historically, 80% of all students in this course attend class
regularly. You must explicitly define any events...

A U.S.-based Internet company offers an online proficiency
course in basic accounting. Completing this online course satisfies
the Fundamentals of Accounting course requirement in many MBA

seven regions of approximately equal population. The course
enrollment values for each of the seven regions are given below.

following manner you answer the questions asked where x = number of
students who fail
