Prisoners with hats in a line 2

Strategy:

For the first person to be asked: If there are $1$ or more people with a bad haircut in front of him, pass. If there are $0$ people in front of him with a bad haircut, say that he himself has a good haircut.

The second person to be asked: If the person before him says that he has a good haircut, pass. If the person before him says pass, and there are $0$ people with a bad haircut in front of him, say that he has a good haircut. If the person before him says pass, and there are $1$ or more people in front of him with a bad haircut, say pass.

The third, fourth, fifth, sixth and seventh person would follow the same algorithm as the second person.

The idea for this is that should anybody say that he has a good haircut, and that he isn't the first person, it means that he sees $0$ person in front of him with a good haircut and the guy before him has seen 1 person in front of him with a good haircut, and this indicates that he is the one with a good haircut.

The only way for this not to work is when the first person sees $0$ people with a bad haircut, causing him to guess his own haircut. The probability of everybody else having a bad haircut is $\frac{1}{2^{6}}$ , and the probability for the first person to guess it wrong is $\frac{1}{2}$ .

Therefore, the probability that this would work is $1-\frac{1}{2^{6}} \times \frac{1}{2}=99.219\text{\%}$

The prisoner at the back states the haircut of the person directly in front of them. The person directly in front of them then guesses the same haircut so assuming the person at the back is telling the truth and isn't blind, they will be correct. Therefore, the strategy is almost certain to work so the answer is >99%.

The last prisoner (who can see everyone) guesses first. He picks any one in front of him (Lets call that person Calvin) , and looks if Calvin's haircut is good or bad. He then guesses that his haircut is the same (good or bad) as Calvin.

If Calvin has a good haircut, the prisoner at the back says he has a good haircut.

If Calvin has a bad haircut, the prisoner at the back says he has a bad haircut.

Next, everyone else guesses the same as the last prisoner.

Calvin will definitely guess his hairstyle correctly.

Since this is certain (unless Calvin tries to sabotage everyone) the probability is 100%, so the best option to pick is ">99%".

But why would Calvin end up in prison? More importantly, What if some prisoners do not like ramen?

Edit: whoops this solution is wrong sorry guys
