When two dice are rolled the sample space is :
Let X denote the sum of the points observed on the uppermost faces of which second face shows 4.
Therefore, the possible values of X are:
Points on dice | (1,4) | (2,4) | (3,4) | (4,4) | (5,4) | (6,4) |
X | 1+4=5 | 2+4=6 | 7 | 8 | 9 | 10 |
Two unbaised dice are rolled at random. Let X denote the sum of the points observed...
2.6 Suppose two dice are tossed and the numbers on the upper faces are observed. Let S denote the set of all possible pairs that can be observed. [These pairs can be listed, for example, by letting (2, 3) denote that a 2 was observed on the first die and a 3 on the second.] a Define the following subsets of S: A: The number on the second die is even. B: The sum of the two numbers is even....
Problem 5. Suppose two dice are tossed and the numbers on the upper faces are observed. Let S denote the set of all possible pairs that can be observed. The pairs can be listed, for example, by letting (2, 3) denote that a 2 was observed on the first die and a 3 on the second. Define the following subsets of S .A The number on the second die is odd. · B: The sum of the two numbers is...

Three six-sided dice are rolled. Let X be the sum of the dice. Determine the range of X and compute P(X = 18) and P(X ≤ 4).
Two dice are rolled. Let X = 1 if the dice come up doubles and let X = 0 otherwise. Let Y = 1 if the sum is 10, and let Y = 0 otherwise. Let Z = 1 if the dice come up both doubles and with a sum of 10 (that is, double 5), and let Z = 0 otherwise. Are X and Y independent?
B. Consider an experiment where two dice are rolled. Define the random variable X as the absolute difference between the face-up values on the two dice. i. Determine the probability that Xis 0. ii. Determine the probability that Xis not 4 iii. Sketch the probability mass function for X.
Problem 4. Two four-sided dice are rolled simultaneously. (a) Let X be the sum of the two rolls. Calculate the PMF and the expected value of . (b) Someone proposes to give you in dollars five times the amount of the sum X that you roll, if you pay A dollars in advance. What should be the amount A in order for you to expect to break even? (c) Repeat parts (a) and (b) for the case where X is...
Two dice are rolled at random. Obtain the probability that the sum of the numbers appearing on the dice is equal to 12.
Two dice are rolled, and the sum of the two dice is recorded. Which sum has the highest probability of occurring?
49. If two fair dice are rolled, find the probability that the sum of the faces is 12.
