what on earth???

OpenStudy (anonymous):

woops

OpenStudy (anonymous):

dice only go from 1-6 1,2,3,4,5,6 1,2,3,4,5,6 6+3, 5+4 are the only possibilities that add up to 9. i'm assuming it wants unique dice, so you could get 3,4,5,6 on the first roll, but then the second roll must be the correct number (1/6) so you have a 4/6 * 1/6 chance, or 1/9

OpenStudy (anonymous):

lets look at a pair of dice and all the combinations

OpenStudy (anonymous):

5 + 4 7+ 2 8+1 These 2 @funinabox

OpenStudy (anonymous):

OpenStudy (anonymous):

okay Nvr Mind

OpenStudy (anonymous):

it can be assumed that when referring to dice, you are talking about a standard 6-sided die, unless told otherwise.

OpenStudy (anonymous):

2/27

OpenStudy (anonymous):

we make a list \[\{(3,6),(4,5),(5,4),(6,3)\}\]

OpenStudy (anonymous):

then count, there are 4 of them divide by the total possibilities which is 36 and get \(\frac{4}{36}\) then reduce if you feel like it
