Sam is rolling a number cube with the numbers 1, 1,2,2,3 and 3 printed on it. What is the probabillity that, if he rolls the cube twice, the sum of the numbers will add to 4?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
