You have two fair 6-sided dice. One is red and the other is blue. When you roll them X=red-blue and Y=red+blue.
a) Find the joint distribution of (X,Y).
b) Find the covariance of X and Y

You roll a pair of fair 6-sided dice: a red die and a blue die. (a) Consider event A: {the outcome of the red die is more than 3} and event B: {the outcome of the red die is less than 5}. Given that event A occurs, what is the probability that event B occurs? (b) Are A and B mutually exclusive (i.e., disjoint)? (c) Are A and B independent? (d) Calculate the probability of event C: {the outcome of...

A blue fair 6-sided dice and a red fair 6-sided dice are rolled at the same time. a) What is the probability of the sum of the dice equals 7, given 1 2 3 4 5 6 at least one of the dice shows a 3? 1 (1.1) (1.2) (1.3) (1.4) (1.5) (1.6) 2 (2.1) (2.2) (2.3) (2.4) (2.5) (2.6) (3.1) (3.2) (3.3) (3.4) (3.5) (3.6) (4.1) (4.2) (4.3) (4.4) (4.5) (4.6) 5 (5.1) (5.2) (5.3) (5.4) (5.5) (5.6)...
You roll two dice, one is red and one is blue. a.) Are the outcomes independent? Why or why not? b.) Find P (2 on red die). c.) Find P (4 on blue die). d.) Find P (2 on red die and 4 on blue die) e.) Find P (3 on red die and 6 on blue die) f.) Find P (2 on red die and 4 on blue die) or (3 on red die and 6 on blue die).
The final answer is 4.472 2. You roll two fair, six-sided dice. Let X be the number on the first die. Let Y be the number on the second die. Calculate E[max(X,Y)], the expected value of the larger of the two numbers. There are several ways you can do this. You should try to do this by applying 2D LOTUS to the joint distribution of X and Y , which is extremely simple. To check your answer, you can use...
Suppose you roll two fair 6-sided dice, and A is the event that both dice are even, and B is the event that the sum of the dice is 9 or more.Hint: 2.4, and the very first problem of this worksheet quiz.(a) Find P(A)(b) Find P(B)(c) Find P(A ∪ B)(d) Find P(Ac ∩ Bc)
If you roll two fair sided six sided dice one time, what are the chances that those of the dice will come up a five?
4. You roll two fair dice, a blue one and a yellow one. a. Find P(even number on the blue die and 3 on the yellow die) b. Find P(3 on the blue die and even number on the yellow die)
You flip a fair coin. On heads, you roll two six-sided dice. On tails, you roll one six-sided dice. What is the chance that you roll a 4? (If you rolled two dice, rolling a 4 means the sum of the dice is 4) O 1 2 3 36 1 2 1 6 + + 1 4 36 1 6 2 2 1 36 + -10 2 . 4 36 + 4 6 2 2
