The probability that the sum of the number of points on the two upward faces is not greater than 7 is () A 1/7 B 1/6 C 1/3 D 1/2

The probability that the sum of the number of points on the two upward faces is not greater than 7 is () A 1/7 B 1/6 C 1/3 D 1/2

Regardless of the order of the two dice
Each chromon has six possibilities. A total of 6 * 6 = 36 basic cases
No more than 7 cases are as follows:
(1,1)(1.2)(1.3)(1.4)(1.5)(1.6)(2.2)(2.3)(2.4)(2.5)(3.3)(3.4)
12 cases, so 12 / 36 = 1 / 3
