Answer 11

Jazy is correct.

Answer 12

but that is only a single fraction

Answer 13

Three scenarios:
- You choose one of the two 'nothing.' The other door reveals nothing and you switch to the money.
- You choose the other 'nothing' and the first 'nothing' is revealed. You switch to the money.
- You choose the money and nothing is revealed, and switch to nothing, losing.

Of course, you win 2/3 of the time in this set up.

Answer 14

If door 1 was opened intentionally BECAUSE it had nothing behind it, you increase your odds to 2/3 if you switch. If it was just opened, you actually still have 1/2 chance with both doors available to you.

Answer 15

Its the Monty Hall principle :)
