Three six-sided dice are rolled. Let X be the sum of the dice. Determine the range of X and compute P(X = 18) and P(X ≤ 4).
Answer it as soon as possible please. Two fair six-sided dice are rolled. Let X be the maximum of the two tosses (for example, if you roll a 2 and a 5, X = 5). Construct a pdf for X, and use it to calculate the following probabilities: p(z) F(x) 1, P(X=3) 3. Construct a cdf for X and use it to calculate P(X s 4).
Problem 4. Two four-sided dice are rolled simultaneously. (a) Let X be the sum of the two rolls. Calculate the PMF and the expected value of . (b) Someone proposes to give you in dollars five times the amount of the sum X that you roll, if you pay A dollars in advance. What should be the amount A in order for you to expect to break even? (c) Repeat parts (a) and (b) for the case where X is...
Two six-sided dice will be rolled once and the numbers (number of dots) on each dice is to be recorded. Define events Еґ the sum of the two dice is 1,1-2,3, , 12. a. List all the outcomes in the Sample Space. Calculate the probability of each event, El, E2, , E12. c. Let A be the event "the sum of the two dice is greater than 6" Calculate P(E10|A) and P(A|E10)
2. An urn contains six white balls and four black balls. Two balls are randomly selected from the urn. Let X represent the number of black balls selected. (a) Identify the probability distribution of X. State the values of the parameters corresponding to this distribution (b) Compute P(X = 0), P(X= 1), and P(X= 2). (c) Consider a game of chance where you randomly select two balls from the urn. You then win $2 for every black ball selected and...
If you add random variables (such as add four dice) the new distribution has a mean and standard deviation of X=X1+X4+X3+X4 The mean and standard deviation for a fair 6-sided die and 10-sided die are: d 3.5 X210 = 5.5 Sa1o 2.031 Problem 1: Let Y be the sum of rolling three 6-sided dice (Bd6) plus two 10-sided dice (2410) Sds - 1.7078 Y = 3d6 + 2d10 la) What is the mean and standard deviation of Y? 1b) Using...
