I recommend using a chart like this one http://bestcase.files.wordpress.com/2011/01/dicediagram.jpg

jimthompson5910 (jim_thompson5910):

and these answer choices seem odd...hmm

OpenStudy (anonymous):

Yah, it has to be put in fraction form

jimthompson5910 (jim_thompson5910):

none of the answer choices are correct

jimthompson5910 (jim_thompson5910):

it should be 5/36 because according to that chart, there are 5 ways to roll a 6 (out of 36 ways total)

@jim_thompson5910 What is the probability that you will roll a total of 6 on your next roll. is what theyre asking

jimthompson5910 (jim_thompson5910):

jimthompson5910 (jim_thompson5910):

So there's a typo somewhere

Here are some simple examples to make sure you get the idea: ... What is the chance of throwing a 7 or 11 when you roll two dice? ... Really we should have counted 7 six times: 1-6, 2-5, 3-4, 4-3, 5-2, 6-1. ... I might win in the short run by luck, but in the long run I am playing a game that is hugely in favor of the casino
