Deadly Choices

A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from magnifying glass.

Funky "Family" answers

Answer to "My Family": 1/3
I have two children. At least one of them is a boy. What is the probability that the other one is a boy as well?
There are four orders the children could have been born.
BB
BG
GB
GG

Of those, three cases have at least one boy in them. Only one of those three has a boy with a brother. So, the answer is 1/3.

Answer to "John's Brother": 1/4A man has two children. One of them is a boy named John. What is the probability that John has a younger brother?
The pairs of children are the same:
BB
BG
GB
GG

If one of the children is a boy, we have the same situation as before:
BB
BG
GB

If one of the boys is named John, there are four possible cases now. Note the first two both come from the original BB possibility.
JB
BJ
JG
GJ

The probability that “John” has a younger brother is 1 in 4.

A Toughie

Question Mark was annoyed with his brother, Skid Mark. Skid thought it would be funny to hide Question's wallet. He told Question to go find it. Skid laid five colored keys in a row. One of them is the key to a room where Question's wallet is. Using the clues, can you determine the order of the keys and which is the right key?

Red: This key is somewhere to the left of the key to the door.
Blue: This key is not at one of the ends.
Green: This key is three spaces away from the key to the door (2 between).
Yellow: This key is next to the key to the door.
Orange: This key is in the middle.
