I need help with these questions:

Question

A survey of 115 children found that

39 liked The Little Mermaid

43 liked 101 Dalmatians

56 liked Mickey Mouse

7 liked The Little Mermaid and 101 Dalmatians

10 liked The Little Mermaid and Mickey Mouse

16 liked 101 Dalmatians and Mickey Mouse

4 liked all three

Question 1: How many students liked ONLY 101 Dalmatians?

Question 2: How many liked the Little Mermaid but NOT Mickey Mouse?

Question 3: How many students did NOT like Mickey Mouse?

**How do I solve this??

Answer 1

Did you make a Venn diagram yet? Put any numbers in it?

Start with the 4 in the middle.
Then work your way out from there.

Answer 2

Ok I think I might understand it now.

1. 16
2. 29
3. 41

Am I correct?
Thanks!
