If you roll 10sided dice, what is the prob that two dice add up to either 19 or 3? I got 4/100 3: (1,2) and (2,1) = 2/100 19: (9,10) and (10,9)= 2/100 2/100 + 2/100 =4/100 Please suggest if my answer is correct or not

If two dice are rolled, yes, else, you find some higher number. Presumably, two dice are rolled.
