I calculated that from a scale of 0 and 1, we have a 0.33 chance of going in in 0 days.
The probability of going in within 1 day is equal to the probability of choosing the second door (0.33) multiplied to the probability of choosing the first door the second time (0.33). 0.33 * 0.33 is equal to 0.1089, so we have a 10% chance of getting in with 1 days.
To get in in 2 days, we would have to choose the second door, and then the first door. Again, this is another 10%
At this point I thought that we have a 53% chance of getting in within two days (33% + 10% + 10%), and 47% of getting in with more than 2 days.
The probability of getting in within 3 days is 0.33 * 0.33 * 0.33, which is around 3%. Considering that the probability of getting in within 4 days would be 1% (0.33 * 0.33 * 0.33 * 0.33), I somehow imagined that of the remaining 47% of chances of getting in within more than two days, the 75% was represented by the probability of getting in within 3 days. The 75% of 47% is 35.2%, which is slightly higher than the chance of getting in within 0 days. The answer is 3.
Given that I lack math background, I wonder if my way of solving this problem is correct (hopefully someone can follow my reasoning).
I think the real value is indeed in the discussion that is being generated after you've consumed an online resource, and I think this is the reason why we have comments here.
I thought that these videos could be helpful in some way for some fellow hackers and that's one reason why I posted the article here.
Another reason is that I'm genuinely interested in knowing about other related videos by reading the always interesting discussions here. I'm also trying to add all these contributions to the post as well.
You may be right about the fact that all these videos have been posted here before. I honestly don't remember about all of them but again I hope they can be useful to someone.
Edit: I'm not a vegetarian by the way.

* Conscious Incompetence: Though the individual does not understand or know how to do something, he or she does recognize the deficit, without yet addressing it.
* Conscious Competence: The individual understands or knows how to do something. However, demonstrating the skill or knowledge requires a great deal of consciousness or concentration.
* Unconscious Competence: The individual has had so much practice with a skill that it becomes "second nature" and can be performed easily (often without concentrating too deeply). He or she may or may not be able teach it to others, depending upon how and when it was learned.
