+660 Dogs in the GoodDog Obedience School win a blue ribbon for learning how to sit, a green ribbon for learning how to roll over, and a white ribbon for learning how to stay. There are 100 dogs in the school.
62 have blue ribbons, 68 have green ribbons, and 60 have white ribbons.
40 have a blue ribbon and a green ribbon; 33 have a blue ribbon and a white ribbon; 36 have a green ribbon and a white ribbon.
15 have all three ribbons.
Fill in the Venn diagram.
I entered the corresponding numbers in the diagram and added 100 in the blank box next to white ribbons after I took the screenshot, but it said it was incorrect. Can someone please help?
