@hotlinebling Hey!
Is the correct answer is C?
If the second and third ones wear 2G, then the first one must be B. but the first person says NO, so the second and the third could be 1B1G/1G1B/2B.
Next, for the second one, if he saw the third one with G hat, then the second one must be B. But the second one says NO, so the third one must be B.
The answer is option (D): The third one wears a Blue hat.
Credit:
Each person can see others hats,
When person 1 and 2 can’t guess the color of hat ,
it means they see two blue or green and blue so the third hat on blind’s head could be blue 33% or green 66%
(B/B/G or B) (G/B/ G or B)
I think this question is wrong

Hey Amin!
There is nothing wrong with it.
We have 3 blue and 2 green hats.
Each person can see the two other’s hats except the blind one.
When each of these individuals see a blue hat wearing by the two others they can’t guess their own hat’s colour.
Your sentences are true
imagine 2 situation
First:
- Blue 2.green 3.blue
Second:
1.blue 2. Blue 3. Green
In both 1 and 2 say no so I think the answer isn’t D or B
If I tell wrong correct my sentences
@AriHoresh
What do you mean by in both 1 and 2 say no? @amin_raei98
In both situation that I told you imagine person 1 and 2 say no (can’t guess the color of hat)
@amin_raei98 I agree with you!
