N=216
事件“所得點(diǎn)數(shù)的最大值為最小值2倍”=A
A={(1,1,2) (1,2,1)(1,2,2) (2,1,1)(2,1,2) (2,2,1) (2,2,4) (2,3,4) (2,4,2)(2,4,3)(2,4,4) (3,2,4) (3,3,6) (3,4,2) (3,4,6) (3,5,6) (3,6,3)(3,6,4)(3,6,5)(3,6,6) (4,2,2)(4,2,3)(4,2,4) (4,3,2) (4,3,6) (4,4,2) (4,6,3) (5,3,6)(5,6,3) (6,3,3)(6,3,4)(6,3,5)(6,3,6) (6,4,3)((6,5,3) (6,6,3)}
M=36
所以P=36/216=1/6
