What is a Venn Diagram ?
Diagrams which represent pictorial relationship of information are called Venn Diagrams. It is used to study sets. It was first used by John Venn
The complete question is
A group of campers were polled about whether they like swimming and whether they like playing baseball. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table. A circle labeled swimming 24 overlaps a circle labeled baseball 18. Overlap is labeled 15. 4-column table with 3 rows. First column has no label with entries likes baseball, does not like baseball, total. Second column is likes swimming with entries a, c, 39. Third column is does not like swimming with entries b, 13, e. Fourth column is labeled total with entries 33, d, 70.
Which values are correct? Select three options. a = 15 b = 18 c = 23 d = 35 e = 31
The image of the Venn Diagram is attached
From the Venn Diagram we can calculate the value of a, b , c , d and e
People who like swimming and baseball = a = 15
People who do not like swimming likes baseball = b =18
People who like swimming and do not like baseball = c = 24
total = d = c + 13 = 24+13 = 47
e =70-39 = 31
Therefore the values of a, b and e are correct.
