To roll one six, you have to roll five numbers that aren't six (seems simple enough). The probability of that is 5^5 / 6^5. Then the last number has to be six, a 1/6 chance, making the probability 5^5 / 6^6. Of course, this can happen in six different ways (rolling a six on any one of your six throws), so the final probability is 5^5 / 6^5. = 3125/7776, approximately a 2/5 chance. The probability of rolling one or more six is the one minus the probability of not rolling a six: The probability of rolling no sixes is 5^6 / 6^6 = 15625/46656... or approximately 1/3. 1 - 15625/46656 = 31031/46656, approximately 2/3.
Yeah, basically a rewording of griff's and starseeker's answers, only more indecipherable.
This is a signature.
The one coin is not a quarter . . . but the other one is . . . making the one coin a dime.
I am the smartest . . . I am the smartest! I AM THE SMARTEST!!! Wait . . . what was the question? I don't know how that gerbil got in your underwear drawer. You haven't had your Weedies, have you?
I don't want to grow up . . . I like it just where I am.

? Why are my arms tied up? Ah, c'mon!
By the way . . . the answer to your insane questions are answered as simply as saying these equally insane answers that actually equal out to being less than many and more than none which in case you didn't realize somehow equals one . . . anyway. The answer is 6. Six is a lucky number. Unless it's combined with another and another and then suddenly stops . . . if six is added to sixty and six hundred, you'd better get on your knees and pray, 'cause that's apparently a very bad sign.
