Question

You keep rolling a fair 6-sided die as long as no value is repeated; in other words, you roll as long as

all values to this point are distinct. When you see the first repeated value, that is your last roll. Let X

be the number of rolls it took. Find P(X = k) for all k.

Suppose you are rolling a fair four-sided die and a fair six-sided die and you are counting the number of ones that come up. What is the probability that both die roll ones? What is the probability that exactly one die rolls a one? What is the probability that neither die rolls a one? What is the expected number of ones? If you did this 1000 times, approximately how many times would you expect that exactly one die would roll...

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).

We roll a fair 8-sided die five times. (A fair 8-sided die is equally likely to be 1, 2, 3, 4, 5, 6, 7, or 8.) (a) What is the probability that at least one of the rolls is a 3? (b) Let X be the number of different values rolled. For example, if the five rolls are 2, 3, 8, 8, 7, then X = 4 (since four different values were rolled: 2,3,7,8). Find E[X].

Suppose Jane has a fair 4-sided die, and Dick has a fair 6-sided die.

1. Suppose Jane has a fair 4-sided die, and Dick has a fair 6-sided die. Each day,they roll their dice (independently) until someone rolls a “1”. (Then the personwho did not roll a “1” does the dishes.) Find the probability that …a) they roll the first “1” at the same time (after equal number of attempts);b) it takes Dick twice as many attempts as it does Jane to roll the first “1”;c) Dick rolls the first “1” before Jane does.

In a game of repeated die rolls, a player is allowed to roll a standard die up to n times, where n is determined prior to the start of the game. On any roll except the last, the player may choose to either keep that roll as their final score, or continue rolling in hopes of a higher roll later on. If the player rolls all n times, then after the nth roll, the player must keep that roll as...
