A person throws two pair 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:

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

In a single throw of two dice, detemine the probability of not getting the same number on the two dice.

Two fair dice are thrown simultaneously.If both die show the same number,then the person wins Rs 15. if the sum of number is 9 , he wins Rs 12. In all other cases,he loses Rs.6 Then the expectation is

If X denotes the number of sixes in throwing two dice, find the expectation of x

In a single throw of two dice, find the probability of getting a doublet of odd numbers.

The sum of numbers on two throws of a dice is 8. Find the probability of getting 3 in at least one throw.
