A number cube is rolled once and the result is recorded. The same number cube is rolled a second time. What is the probability that the sum of the rolls is greater than 7?

My answer is different. How did you get 5/6 ?
I divided the number of possible outcomes in which the sum is greater than seven by the total number of possible rolls.
(Remember to count them all. For example, there are two ways to get a sum of 3: first die shows 1 and second die shows 2 OR first die shows 2 and second die shows 1, etc.)

No, you asked me my answer and I gave it to you, so why won't you give me your answer. Apparently you don't have an answer, because you know I'm correct, so don't bother. I'm a tiger not a wolf!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You apparently did not read this:
Welcome to FreeMathHelp.com!
Please take the time to read the following before you make your first post. It will help you to get your math questions answered promptly and in the most helpful manner.
Don't post a list of homework problems. Please show us any work you have done towards answering the problem, and try to explain what specifically is giving you trouble. Also, please try to limit the number of questions you ask to a reasonable number per day. There's no exact limit, but try to be polite and not abuse the service.
Try to use halfway-decent English. No, this isn't Englishhelp.com, but you'll get more help if you spell correctly. Actually, I don't care if you spell a few words wrong, but the IM speak will probably cause some people to skip over "ur" question. If we can't read it, we can't help you
Be nice. Everyone here is a volunteer, so treat them with respect and we will (probably) be nice in return. If we aren't... then it's probably just been a long day. If you have any conflicts, please contact me personally rather than starting a flamewar on the forum.
Don't spam. Okay, so the spammers aren't going to read this anyway, but it's probably good to have it in writing.
Post to an appropriate category. Questions about derivatives (calculus) do not belong in "Beginning Algebra". Questions about finding the area of a circle (geometry) do not belong in "Other Math". Please show appropriate care and consideration.
Preview or edit your posts for clarity. When composing your message, you may include formatting that doesn't "take" when the message is finally posted. For instance, the forum script strips away spaces at the beginnings of lines. Kindly "edit" your post to correct errors if they occur, and "preview" your posts to minimize errors. (For formatting advice, try Karl's Notes or "Formatting Math as Text".)
Post the complete text of the exercise. This would include the full statement of the exercise and its instructions, so the tutors will know what you are working on. If there is a graphic or table or some other non-textual information necessary to the exercise, include a detailed description.
Show all of your work. If you've shown no work at all, the tutors may assume that you're needing help getting started, and may suggest only how to do the first step. Even if you're asking only about the very end of the solution process, still include all of your intermediate steps. Errors may have occurred earlier than you'd realized; correcting part (b) may clear up your confusion on part (d).
Have patience. There is no paid staff waiting on-hand to give instant replies. Many of the volunteer tutors have "real" jobs, and they all have to sleep from time to time. The people "viewing" your posts may be fellow students. Please don't be offended if there are "views" but no replies. It may take hours, even days, for a tutor, qualified in your topic's area, to respond.
