P=1–P(all three ARE the same)

P(same)=6*(1/6*1/6*1/6)=6/216=1/36

P(three ARE NOT the same)=1–1/36=35/36

Does this not mean all the three dices have three different numbers?

Am I misunderstanding the question? If so, how my understanding will
be constructed as question?

210/216 , is absolutely correct .. there are only 6 possibilities where are 3 will be the same numbers out of the 216 possible so , effectively 210 for which all three will " not " be the same... and hence the answere[/img]

Let's spice it up a bit. If the same 3 fair dice are thrown, can anybody find what is the probability that NO TWO numbers are the same?

To Paul, 2 out of three dices we can select in 3 ways, 6 possibilities to select numbers for the pair and 5 for the single dice or 5x6x3=90 ways when 2 are the same. 216-90=126/216 but the option that 3 are the same is also included. If the question is no 2 AND 3 are the same then it should be 120/216.
