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.
A fair six-sided die is tossed four times and the resulting sequence of numbers is recorded. A) What is the probability of the event E that either all four numbers are not equal or none of them is 3 or 6? B) What is the probability of the event E that either all four numbers are equal or none of them is 2? C)What is the probability of the event E that either all four numbers are not equal and...

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.
A fair six-sided die is rolled five times. Find the chance of the event: Exactly one roll is a six.

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 six-sided die is to be rolled three times. Assume the rolls are independent and that the die is fair. - The probability that all three rolls result in an even number is: A) 1.0 B) 0.75 C) 0.25 D) 0.125 - The probability that at least one of the rolls is an even number is: A) 0.125 B) 0.333 C) 0.750 D) 0.875 - The events A = exactly two of the rolls are even and B = exactly...
. [8] A gambler suspects a six sided die is "loaded" meaning the center of mass of the die is not in the center but toward one face, thus shifting the probability of each face from 1/6 each to something else. In the course of 600 trials, she observes (122 "aces", 103 "twos.98 "threes 95 "fours", 105 "fives" and 77 sixes". On a die, the even and odd spots are on opposite sides so one way we could look at...
