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

In a game, a man wins Rs 100 if he gets 5 or 6 on a throw of a fair die and loses Rs 50 for getting any other number on the die. If he decides to throw the die either till he gets a five or a six or to a maximum of three throws, then his expected gain/loss (in rupees) is: (a) 400/3 gain (b) 400/9 loss (c) 0 (d) 400/3 loss
