Answer:
The answer to your problem is: 11
Step-by-step explanation: To solve this problem we need to draw a Venn diagram
Data
Population 32 fifth graders
17 students liked carrots
20 students liked green beans
How many said they liked both vegetables
As the population that does not like neither carrots nor green beans, then the population under research is : 32 - 6 = 26
Then 26 is the combination of graders that like only carrots, only beans or both.
And the total of carrots must be 17, the total of beans must be 20, then we combine this numbers in order to get 26
For example:
carrots green beans both total
