6. A six sided balanced die is rolled 30 times. The uppermost face is observed on each roll.
A. Find the probability that each of the six sides shows up exactly five times.
b. Find the probability that the die shows a 1 exactly five times and a 2 exactly 10 times.

What is the probability that a fair six-sided die rolled five times comes up 6 exactly once?
A fair six-sided die is rolled five times. Find the chance of the event: Exactly one roll is a six.
a) If a single six-sided die is rolled five times, what is the probability that a 6 is thrown exactly three times? b) A person receives an average of one e-mail message per half-hour interval. Assume that e-mails are received randomly in time, find the probabilities that in a particular hour 0,1,2,3,4,5 messages are received.
6. A fair six sided die is rolled three times. Find the probability that () all three rolls are either 5 or 6 (6) all three rolls are even (c) no rolls are 5 (d) at least one roll is 5 (e) the first roll is 3, the second roll is 5 and the third roll is even
A single six-sided die, whose faces are numbered 1 to 6, is rolled n times. The die is fair, each face is equally likely to land upward when the die is rolled. Let X be the number of times that the number on the upward face of the die is 1. Find the mean and the standard deviation of the random variable X.
Suppose I asked you to roll a fair six-sided die 6 times. You have already rolled the die for 5 times and six has not appeared ones. Assuming die rolls are independent, what is the probability that you would get a six in the next roll? 1/6 1/2 5/6 0 1
A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment and find the probability of the given event.One die shows a 5, and the other is a number less than 2.
Suppose that a balanced, six-sided die has been altered so that the faces are 1, 2, 3, 4, 5, and 5. If the die is tossed five times, and the number on the uppermost face is recorded each time, what is the probability that the numbers recorded are 1, 2, 3, 4, and 5 in any order? (Round your answer to four decimal places.)
A regular six-sided die is rolled 9 times. What is the probability of getting a 1 or 6 on exactly 7 of those rolls?
A six-sided die is rolled 500 times. Use the CLT to approximate the probability that the sum of the rolls exceeds 1800.You’ll need to know the expectation (μ) & variance (σ2) of a single roll.
