(In reply to Solution to half the problem by Sohini)

the least likely total is 90, but then again the least likely total is also 89, 88 etc etc... because you have to stop once you get higher than 15.... there are 6 numbers on a die, so the largest sum you can ever achieve is 20......... 21+ has a 0% probability....
