Question

A group of 50 people were asked their gender and if they liked cats. The data from the survey are shown in the Venn diagram. Determine the value for each variable in the two-way table.

Answer 1

a = 13,

b = 28,

c = 6,

d = 22,

e = 31

Explanation:

E = 15 +16 = 31

6 males like cats ( the middle section) so C = 6

d = 6 +16 = 22

a = 19-6 = 13

b = 50-22 = 28

so in order: a = 13, b = 28, c = 6, d = 22, e = 31
