a) (4 pts) Create a valid probability model for the simultaneous roll of two fair 3-sided dice (yes, they do exist) that have sides with a 1, 2, and 3 on the sides of the dice. b) (2 pts) What makes your probability model valid? c) (4 pts) Using your probability model from part a, what's the probability you will get a roll of the two dice with only 1s or 2s (i.e. no 3s are showing)? Show your work. Express your answer as a decimal using 2 decimal places.

Step 1
Step 1: The sample space for rolling two 3-sided dice is: $$S = \{(1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3)\}$$ Show more…

The newest invention is a three-sided die. On any roll of this die, the result is 1 with probability 1/2, 2 with probability 1/4, and 3 with probability 1/4. Consider a sequence of six independent rolls of this die. A. Find the probability that exactly two of the rolls result in a 3. B. Given that exactly two of the six rolls resulted in a 1, find the probability that the first roll resulted in a 1. C. We are told that exactly three of the rolls resulted in a 1 and exactly three rolls resulted in a 2. Given this information, find the probability that the six rolls resulted in the sequence (1,2,1,2,1,2).

Explain the steps please. (a) [2 pts] In order to be a valid probability model? What probability do we have at 2? i.e., what is P(X=2)? Explain your answer. (b) [2 pt] Is this X a finite random variable or a continuous random variable? Explain your answer. (c) [2 pts]What is the probability that the sum of the two roll outcomes is at least 5? (d) [2 pts]What is the probability that P(3<X<7)? (e) [2 pts] What is the probability that P(3≤X≤7)

Problem 5.4. I have three fair dice: one is 6-sided, one is 8-sided, and one is 12-sided. Each n-sided die has numbers 1 through n on its sides, and each side is equally likely to come up. I roll the three dice at the same time. (a) What is the probability that I roll the same number on all three dice? (b) I pick one of the dice at random, with all three equally likely to be picked. I roll it and it comes up "4". What is the probability that the die I rolled was the 6-sided one? (c) What is the probability that the smallest number I roll is at least 3? Hint: "smallest number is at least 3" = "all 3 dice show 3 or higher". (d) What is the probability that the product of the three numbers I roll is even? Hint: the product of two odd numbers is odd; the product of an even number with any other number is even.
