Actually it is wrong in that it is severely misleading. Even putting asside the crooked dice that Eladrin mentioned, 10-60 would make a logic person assume a random number between 10 and 60 was generated with an equal probabilty of any result. That is false if it is 10d6 because statistically 10d6 will cluster around the average of 30, as any dice player will tell you. The result of 10d6 is under a normal distribution curve. This is critical information that is missing.
Now you add to that the crooked die and it becomes even more misleading. because that moves the curve to the right, meaning 10d6, which is really 10d3+30 would have a normal distribution centred the 45 range, with no chance of a 10-39 result.
