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, $55$ have green ribbons, and $63$ have white ribbons. $32$ have a blue ribbon and a green ribbon; $31$ have a green ribbon and a white ribbon; $38$ have a blue ribbon and a white ribbon. $16$ have all three ribbons. How many dogs have not learned any tricks?

NOW, before you all scream at me and say EP already solved something exactly like this, he got the answer $6$ which was wrong and he didn't provide explanation.

Please solve and have a happy CHRISTMASSSS!

Nevermind! I got it ._. made a silly mistake! The answer is actually $5$ and not $6$ as EP stated, but that forum is locked so I guess people will get stuck with the wrong answer :(

Well, Mr. BB, I was just about to chime in with a troll post... when your first comment popped up.  I paused because it would look like I was stepping on your comment. I don’t mind kicking your comments, but I don’t like stepping on them, because it takes a long time to clean my shoes.   

 

But I did write this before you posted... so I’ll put on my galoshes before I step on it. ...and you are right; it is good.   

------------------

 

Well ... MSFL, you should post your answer in detail.  You’ll then be a contributor, instead of just a homework answer moocher. 

 

BTW, EP’s answer isn’t wrong. You are just a careless dolt.  The question EP answered is not the same one that you posted. In the question EP answered, 39 have a blue ribbon and a white ribbon. For your question, 38 have a blue ribbon and a white ribbon.   So, no one will be stuck with the wrong answer, but the forum may be stuck with a careless dolt.Dolt Forever

Start with this Venn diagram.

Put the middle one in first and then work outwards.
