Answer:
0.6667 = 66.67%
Step-by-step explanation:
If each number cube has 6 numbers, the two cubes have a total of 6 * 6 = 36 results.
To have equal numbers in each cube, the cases are:
(1,1), (2,2), (3,3), (4,4), (5,5), (6,6) -> 6 cases
To have a odd sum, the cases are:
(1,2), (1,4), (1,6),
(2,1), (2,3), (2,5),
(3,2), (3,4), (3,6),
(4,1), (4,3), (4,5),
(5,2), (5,4), (5,6),
(6,1), (6,3), (6,5). -> 18 cases
So we have a total of 18 + 6 = 24 cases, then the probability is:
P = 24 / 36 = 0.6667 = 66.67%
simplified it would be -
