Question 824676: 4. The following table shows the number of students in three different degree programs and whether they are graduate or undergraduate students:
Undergraduate Graduate Total
Business 150 50 200
Engineering 150 25 175
Arts & Sciences 100 25 125
400 100 500
a. What is the probability that a randomly selected student is an undergraduate?
b. What percentage of students is engineering majors?
c. If we know that a selected student is an undergraduate, what is the probability that he or she is a business major?
d. A student is enrolled in the Arts and Sciences school. What is the probability that the student is an undergraduate student?
e. What is the probability that a randomly selected student is a graduate Business major?

You can put this solution on YOUR website! The following table shows the number of students in three different degree programs and whether they are graduate or undergraduate students:
...........Undergraduate Graduate Total
Business .......150....... 50..... 200
Engineering.... 150....... 25..... 175
Arts & Sciences 100....... 25..... 125
Totals..........400...... 100..... 500
a. What is the probability that a randomly selected student is an undergraduate?:: 400/500 = 4/5
--------------------------------------
b. What percentage of students are engineering majors?:: 175/500 = 7/20
--------------------------------------
c. If we know that a selected student is an undergraduate, what is the probability that he or she is a business major?:: 150/400 = 3/8
--------------------------------------
d. A student is enrolled in the Arts and Sciences school. What is the probability that the student is an undergraduate student?:: 100/125 = 4/5
--------------------------------------
e. What is the probability that a randomly selected student is a graduate Business major?:: 50/500 = 1/10
