Not in that case ! Very simple : you have 100 possible values, ranging
from 1 to 100 ... each value correspond to a single dice configuration
(it you rool 2 and 5 you get 25 and you have no other way to get 25).
Thus the probability of each value is 1/100 ... and all values are
equiprobable !

And of course you can generalize the result ^^
You want a d1000 ? take 3 d10
You want a d36 ? take 2 d6 and calculate : 6*(d6-1) + d6
You want a d144 ? take 2 d12 : 12*(d12-1) + d12
