i. Consider a weighted 6-sided biased die that is twice as likely to produce any even outcome as any
odd outcome. What is the expected value of 1 roll of this die? What is the expected value of
the sum of 9 rolls of this die?
ii. Let X denote the value of the sum of 10 rolls of an unweighted 6-sided die. What is Pr(X =
0 mod 6)? (Hint: it is sufficient to consider just the last roll)
iii. What is the expected number of distinct faces that will be observed in m rolls of an n-sided
unweighted die? (Hint: dene indicator variable Xi which is 1 if the i'th face is never observed,
and use linearity of expectation). You may leave your answer as an expression in terms of m
and n.

Consider the setting where you first roll a fair 6-sided die, and then you flip a fair coin the number of times shown by the die. Let D refer to the outcome of the die roll (i.e., number of coin flips) and let H refer to the number of heads observed after D coin flips. (a) Suppose the outcome of rolling the fair 6-sided die is d. Determine E[H|d] and Var(H|d). (b) Determine E[H] and Var(H).

You are conducting an experiment while utilizing a six-sided die that does not produce any sort of bias towards any of the 6 numbers. You will roll this die until you achieve the number "six." A.) What is the probability that you have to roll n times? That is, you fail to roll a "six" n-1 times, then roll a six on the nth roll. B.) Sum all of the probabilities from part A. What is the significance of this...

Problem 5. A lopsided six-sided die is rolled repeatedly, with each roll being independent. The probabil- ity of rolling the value i is Pi, i = 1, … ,6. Let Xn denote the number of distinct values that appear in n rolls. (a) Find E|X, and E21 (b) What is the probability that in the n rolls of the dice, for n 2 3, a 1, 2, and 3 are each rolled at least once?

1. I have a six sided die. My suspicion is that the die is not fair, rather it is weighted to rol twos more often then expected with a fair die. To investigate this I roll the die 100 times. In those 100 rolls, I observe 21 twos.

A dice game is played with two distinct 12 sided dice. It costs $3 to roll the pair of dice one time. The payout scheme is as follows 1. Sum of 13 pays $10 Sum of 11 or 15 pays $6 Sum of 7, 9, 17, or 19 pays $3 Any other roll doesn't pay. What is the expected gain/loss after playing the game one time?

What is the expectation (or expected value) of the following: Consider a casino game where the player rolls a 6-sided dice and receive $10 if the roll is 1 or 6, and $0 for any other roll. Let X the amount won after playing the game once. Additionally, what’s the lowest amount the casino can charge to play the game and still make a profit on it over time?
