A random number N of dice is thrown. Let Ai be the event that N =...
4. Suppose we roll N dice, where N is a random number, with P ( N = i ) = 2 − i for i ≥ 1 . The sum of the dice is denoted by S . Find the probability that: (a) (5 points) N = 2 given S = 4 ; (b) (5 points) N is even; (c) (5 points) S = 4 given N is even.
1. Two dice are thrown. Let E be the event that the sum of the dice is odd, let F be the event that at least one of the dice lands on 1, and let G be the event that the sum is 5 . List the outcomes ina. E ∩ Fb. E ∪ Fc. E ∩ F'd. E ∩ F ∩ G
.1. A pair of fair dice is thrown, what is the probability that the sum of the two numbers is greater than 10. 2. A pair of fair dice is thrown. Find the probability that the sum is 9 or greater if a. If a 6 appears on the first die. b. If a 6 appears on at least one of the dice.
Two standard dice are rolled, one red, one green. Let A be the event that the red die is a either a 4 or a 6, let B be the event that the sum of the dice is grenter than 5 a. Find P(A) c. Find P(A | B) e. Find P(An B) . Find P(A'I B) 10. b. Find P(B) d. Find P(B | A) f. Find P(AnB') h Find P(A'UB) Are events A and B dependent or independent?...
5. What is the correct set notation for the event that "the sum of the two dice is not less than 5 if at least one die lands with 3 facing up"? 6. Calculate the probability that the sum of the two dice is not less than 5 if at least one die lands with 3 facing up. 7. Are A and B independent? Explain your reasoning. Use for Questions 1-7: Hector will roll two fair, six-sided dice at the...
Questions 1-7: Hector will roll two fair, six-sided dice at the same time. Let A = the event that at least one die lands with the number 3 facing up. Let B = the event that the sum of the two dice is less than 5. 1. What is the correct set notation for the event that “at least one die lands with 3 facing up and the sum of the two dice is less than 5”? 2. Calculate the...
Let S(sub k) denote the event that the sum of three fair typical six-sided dice is k. Assume that one die is red, one is green and one is blue so that the three dice are distinguishable. Compute P(S(sub k), for all values of k.
I know Pk~1/k^5/2 just need the
work
Problem 1. Suppose that a fair six-sided die is rolled n times. Let N be the number of 1's rolled, N2 be the number of 2's rolled, etc, so that NN2+Ns-n Since the dice rolls are independent then the random vector < N,, ,Ne > has a multinomial distribution, which you could look up in any probability textbook or on the web. If n 6k is a multiple of 6, let Pa be...
Exercise 4.8. Dice. You roll two dice. Let A belthe event that the sum of the dice is an even number. Let B be the event that the two results are different. If B has occurred, what is the probability A has also occurred?
(4) Consider rolling three dice. Let X1, X2, and X3 the values which appear on the three dice, respectively. Let Y be the maximum out of all three dice. (a) Find the conditional PMF py)xi (yr) (b) Find the probability that the maximum of all three dice is 4 given that the first die is a 3. (c) Find the probability that the maximum of all three dice is 3 given that the first die is a 3
