Re: Re: Re: Probability question

So the probability of exactly two would be nil.

Re: Re: Probability question

I would think that if two were returned correctly, that all three would be returned correctly.

Re: Probability question

Since 6/9 is equal to 4/6,   

and 4/6 is the probability of getting at least one of the hats returrned correctly,

 

6/9 is the probability of getting at least one of the hats returned correctly.

 

Now, what is the probability of getting exactly two of the hats returned correctly?

Hint:  This is one of my trick questions.
