In order to generate proper fractions, one standard six-sided die is rolled twice in a row. The result of the first roll is recorded as the numerator, and the result of the second roll is recorded as the donominator. The fractions are reduced, if possible. How many distinct fractions between 0 and 1 can be generated by this method?
A 15
B 11
% q% X. g7 }9 q" nC 9
0 W3 L6 E/ Z9 \, X  f0 Q2 L D 8

就是说投一个骰子，第一次出来的做分子第二次出来的做分母问能搞出多少个不同大小的分数咯，小于一大于零的
