3 Mislabeled Boxes

You have three boxes. One has only red marbles, one has only blue marbles and the third has an equal number of red and blue marbles. The labels on the boxes have intentionally been switched so that each box is now marked incorrectly.

Your job is to relabel the boxes correctly. Of course you could just look in the boxes to find out which labels match, but can you do it without looking into each box? Reach into any one of the boxes and select one marble. Can you now correctly label all three boxes? If not, select a second marble from any box. What is the fewest number of marbles you need to inspect in order to correctly label each box?

The Passwords

A man worked for a high-security institution, and one day he went in to work only to find that he could not log in to his computer terminal. His password wouldn’t work. Then he remembered that the passwords are reset every month for security purposes. So he went to his boss and they had this conversation:

Man: “Hey boss, my password is out of date.”
Boss: “Yes, that’s right. The password is different, but if you listen carefully you should be able to figure out the new one: It has the same amount of letters as your old password, but only four of the letters are the same.”
Man: “Thanks boss.”

With that, he went and correctly logged into his station. Can you figure out the old and new passwords?
