Thread: Three dices problem, stuck at extracting biggest occurence to return frequency

Hello,
First off, I am a complete beginner, with only - I'd say 60 - 70 hours of practice overall.
I have to write a code for the following problem: you have three dices (typical, 6 faces) which you have to roll as many times as the user chooses with an initial input (like in "how many times do you want to roll the dices" kind of input), and I have to generate a simple table with the first column being all possible sum-of-the-three combinations (from 3 to 18, obviously) and in the second column the frequency of each possible combination (hence the frequency of sum=3, frequency of sum=4 and so on till the frequency of sum=18). While I am able to perform everything right and get random number of sums for various number of rolls, it seems over my head to figure out the code to get the frequency for each of the 16 possible sums. I am drooling for a little bit of help here. Anybody? Really appreciated

Thank you Jim, yes, the pattern of the sum is irrelevant for my query, it does not matter the "composition" of a sum. And yes, I did it on paper, I simply don't know how to translate the logic in code lines, that is the problem. As an example, if I choose to roll the dices 11 times, I get 11 different sums, with a certain pattern of frequencies, like (again, just as an example) 2 times sum=4, 3 times sum=5, 3 times sum=6 2 times sum=8 and 1 time sum=11. Well, my table should look something like - first column, from top to bottom, 3, 4, 5, 6,... 18, second column, top to bottom (for this example) 0 (because sum=3 didn't appear in my roll), 2 (because 4 showed up 2 times), 3, 3, 0 (for 7, because it didn't show in the roll), 2, 0, 0, 1, 0, 0, etc. So the question is how do I code the total number of times a certain sum happened to appear in a particular roll.
Anyways, thank you for the reply

Yes, that is correct if you think in terms of probabilities, but I don't have to make a table with the probable number a certain sum might show up in a certain number of rolls (which is a pure mathematical/probabilistic approach, and, indeed, you don't even need to roll dices for that), rather I need to extract the number of times a certain type of sum shows up in a finite number of rolls (number which will absolutely differ from a series of rolls to the other, depending on the random generator). As an attempt to be crystal clear, if I make ten sets of 15 rolls and I fill up the table for each set of rolls, the columns will be different every single time, even if the tendency will be for the sums towards the middle to be the most frequent (the most number of combinations possible) while the sums at the extremes (3 and 18) will tend to be less frequent because of the limited possible combinations, right?
The problem states "show the number of times each sum appears on a certain set of rolls", which I interpreted as frequency. In other words, if in a set of 20 rolls the sum of 11 appears 5 times, I would call that the "frequency" of sum 11 showing up in the results. Am I interpreting it wrong?
Thank you Jim
