lets count the number of ways to roll a total of 4
there are not so many we can't list them
\[(1,3),(2,2),(3,1)\]
OpenStudy (anonymous):
there are 36 possible rolls all together, so the ratio is
\[\frac{3}{36}\] which reduces
OpenStudy (anonymous):
making your answer
\[\frac{1}{12}\]
OpenStudy (anonymous):
