A person throws two fair dice. He wins Rs. 15 for throwing a doublet (same numbers on the two dice), wins Rs. 12 when the throw results in the sum of 9, and loses Rs. 6 for any other outcome on the throw. Then the expected gain/loss (in Rs.) of the person is :

1. 4 1 loss
2. 2 1 gain
3. 2 1 loss
4. 2 gain

Correct answer: 2 1 loss
