Consider rolling both a fair four-sided die numbered 1-4 and a fair six-sided die numbered 1-6 together. After rolling both dice, let X denote the number appearing on the foursided die and Y the number appearing on the six-sided die. Define W = X +Y . Assume X and Y are independent. (a) Find the moment generating function for W. (b) Use the moment generating function technique to find the expectation. (c) Use the moment generating function technique to find...

Consider a fair four-sided die numbered 1-4 and a fair six-sided die numbered 1-6, where X is the number appearing on the four-sided die and Y is the number appearing on the six-sided die. Define W=X+Y when they are rolled together. Assuming X and Y are independent, (a) find the moment generating function for W, (b) the expectation E(W), (c) and the variance Var(W). Use the moment generating function technique to find the expectation and variance.

2 fair four-sided dice with faces numbered 1, 2, 3, 4 are rolled. Random variable D is the nonnegative difference |X2 −X1| of the numbers rolled on the 2 dice and Y is a Bernoulli random variable such that Y = 0 if the sum X1 +X2 is even and and Y = 1 if the sum is odd. a. Find joint probability mass function of D and Y. b. Are D and Y dependent or independent? How do you...

a dice can have 6 sides and are numbered 1,2,3,4,5, and 6. The odds of getting an odd number are the same. The chance of getting an even number is the same. The chance of getting an odd number is twice the chance of getting an even number. a. Determine the opportunity to get the number 3. b. The dice is thrown three times. Determine the odds of getting two numbers 5 and one number 4. c. The dice is...

Dice Game Rules: 2 - 4 players Each player has 5 Dice. The dice have 6 sides. Each player rolls their dice, and the dice statistics are reported: Sum, number of pairs (and of what), and "straights" - (all dice in order - e.g. 1,2,3,4,5 or 2,3,4,5,6) Player 1 might roll 2,2,3,4,4 so the results would be: Sum: 15, 1 pair (2), 1 pair (4) Player 2 might roll 1, 1, 4, 6, 6 so the results would be: Sum:...

Take a simple experiment of rolling a pair of balanced dice. Each die has six sides, each side contains one to six spots. Let us define the random variable x to be the sum of the spots on the two dice. Display the probability mass function and the distribution function for the random variable x.

Example 4: A fair six-sided die is rolled six times. If the face numbered k is the outcome on roll k for k = 1, 2, 3, 4, 5, 6 we say that a match has occurred. The experiment is called a success if at least one match occurs during the six trials. Otherwise, the experiment is called a failure. The outcome space is O = {success, failure}. Let event A = {success}. Which value has P(A)? **This question has...

(5) A fair 6-sided dice is rolled twice. The fairness of the dice consists of the following facts: (i) no face of the dice is likelier to be rolled than any other (so a roll of a 5 and a roll of a 3 are equiprobable) and (ii) the dice has no “memory” - each roll is independent of any other. 5.1: What is the probability that you’ve first rolled a 3 and the pair of rolls sums to something...

Roll two fair dice. Each die has six faces. A. Let A be the event that either a 3 or 4 is rolled first followed by an odd number. P(A) = Round your answer to two decimal places. B. Let B be the event that the sum of the two dice is at most 7. P(B) = Round your answer to two decimal places. C. Are A and B mutually exclusive events? (Yes or No) D. Are A and B independent or...
