Quiz: Venn Diagram and Probability Review

Ms. Stringer conducted a survey of his 9th grader homeroom.  17 students are taking both Econ and Business.  19 students are only taking Econ.  18 students are only taking Business.  16 students are taking other courses.

Construct Venn Diagram. Which one of the followings is correct for the given Venn picture.

• i = 16, ii = 17, iii = 18. iv = 19

• i = 19, ii = 18, iii = 17. iv = 16

• i = 19, ii = 17, iii = 18. iv = 16

• i = 16, ii = 18, iii = 17. iv = 19

Mr. Jones conducted a survey of his 9th grader homeroom.  20 students are taking both Econ and Business.  30 students are taking Econ (subtract to 20).  15 students are only taking Business.  25 students are taking other courses.
