Find a solution to the third problem.
Assuming that 1 is the same as the second dice and the third dice is different, then:
The number of the first dice is arbitrary and the probability is1;
The second dice has the same number of points as the first, and the probability is1/6;
The third dice is different from the first two with a probability of 5/6;
So the total probability is1× (1/6) × (5/6) = 5/36.
.
Assuming that 1 is the same as the third dice, it also gets 5/36;
Assuming that the second and third dice are the same, 5/36 is also obtained;
.
So the final probability is 3×(5/36)=5/ 12, so choose B.
