What is the probability of obtaining a sum of at least 7 when rolling a pair of dice?
Answer:
The total number of possible outcomes is 36 and there are 21 possible "winners." Therefore, the probability of winning is 21 out of 36 or 21 divided by 36. If you do the division, the answer is 0.58333333 or you have a 58.333333% chance that on a single roll you will get a total of 7 or greater, I hope that helps
