'Suppose that fair die is rolled n times We say that there is an increase at the ith place if result on the + Fst roll is greater than the result On the ith roll. Let be a random variable representing the number of increases Find Elx]:'
Added by Daniel P.
Step 1
Since the die is fair, the probability of getting any number from 1 to 6 is 1/6. Therefore, the probability of having an increase at the first roll is 5/6 (since there are 5 numbers greater than the first roll). Show more…

A fair die is rolled repeatedly, and a running total is kept (which is, at each time, the total of all the rolls up until that time). Let pn be the probability that the running total is ever exactly n (assume the die will always be rolled enough times so that the running total will eventually exceed n, but it may or may not ever equal n). (b) Find pn

Suppose we roll a fair six-sided die and sum the values obtained on each roll, stopping once our sum exceeds 369. Approximate the probability that at least 98 rolls are needed to get this sum. Probability: 0.93796138
