From the given table, let's make a venn diagram to show the number of animals that are dogs and are over 8 years old.
We have the table:
Species Age
Dog 10
Cat 9
Dog 9
Cat 5
Dog 5
Cat 13
Cat 13
cat 9
Dog 3
Dog 11
Cat 11
Cat 10
Using the table, we can deduce the following:
• Total number of dogs = 5
,
• Number of dogs that are over 8 years old = 3
,
• Number of dogs under 8 = 2
,
• Number of cats = 7
,
• Number of cats over 8 years = 6
,
• Number of cats under 8 = 1
,
• Total number of animals over 8 = 3 + 6 = 9
Now, let's draw the venn diagram:
