"At a high level, in probability, a convolution is the way to determine the distribution of the sum of two random variables." Probability of a certain sum value s is: sum of probabilities of all (a,b) with a + b = s (a: value from first input distribution. b: value from second input distribution) with probability (a,b) = probability(a) * probability(b)
