Consider the following experiment: Roll two fair, four sided dice. Consider the following discrete random variables:...
Roll two fair four-sided dice. Let X and Y be the die scores from the 1st die and the 2nd die, respectively, and define a random variable Z = X − Y (a) Find the pmf of Z. (b) Draw the histogram of the pmf of Z. (c) Find P{Z < 0}. (d) Are the events {Z < 0} and {Z is odd} independent? Why?
Suppose you roll k >= 1 fair dice. Let X be the random variable for the sum of their values, and let Y be the random variable for the number of times an odd number comes up. Prove or disprove: X and Y are independent. *Please use the concept of independent random variables
You roll two six-sided fair dice. a. Let A be the event that either a 4 or 5 is rolled first followed by an even number. P(A) = Round your answer to four decimal places. b. Let B be the event that the sum of the two dice is at most 5. P(B) = Round your answer to four decimal places. c. Are A and B mutually exclusive events? d. Are A and B independent events?
Consider the experiment of rolling six six-sided dice. Let Yi each be random variables given by the following functions of the outcomes in the experiment described above. For each of these new random variables Yi given below, describe (1) the new sample space associated with Yi (i.e., SYi = Yi(S)) and (2) the Probability function P (Yi = k) for value of k in SYi . (a) Y1 is the number of even integers in the sequence. (b) Y2 is...
Fair diced, which is unbiased. Each throw is independent. Step 1. You roll a six-sided die. Let X be the (random) number that you obtain. Step 2. You roll X six-sided dice. Let Y be the total number (sum) that you obtain from these X dice. Find E[Y], rounded to nearest .xx.
Problem #3: 5 fair 12-sided dice are rolled. (a) [3 marks] Find the conditional probability that at least one die lands on 3 given that all 5 dice land on different numbers. 6) [2 marks] True or False: If X is the maximum of the 5 numbers from one roll, and Y is the minimum of the 5 numbers from one roll, then X and Y are independent random variables.
dice is unbiased. Throws independent. Step 1. You roll a six-sided die. Let X be the (random) number that you obtain. Step 2. You roll X six-sided dice. Let Y be the total number (sum) that you obtain from these X dice. Find E[Y] rounded to nearest .xx.
Suppose that Adam rolls a fair six-sided die and a fair four-sided die simultaneously. Let A be the event that the six-sided die is an even number and B be the event that the four-sided die is an odd number. Using the sample space of possible outcomes below, answer each of the following questions.What is P(A), the probability that the six-sided die is an even number?What is P(B), the probability that the four-sided die is an odd number?What is P(A...
Question 6 3 pts Exercise f. Consider the experiment in which three fair (and independent) dice are rolled: a red 4-sided die, a white 6-sided die and a blue 8-sided die. What is the probability that the highest rollis exactly 4? Question 7 3 pts Exercise g. Consider the experiment in which three fair (and independent) dice are rolled: a red 4-sided die, a white 6-sided die and a blue 8-sided die. What is the probability that the 4-sided die...
