Thread: Graphing two data sets

I'm attempting to graph the probability of each outcome of adding one number from each of two data sets.

For instance:
Data set One:
77,65,88,56,90

Data set two:
58, 65, 70, 100, 80

So I want the possible outcomes of adding one number from data set one to one number from data set two. I remember doing something like this in High School, but I've lost the name for it, and forgotten how to do it.

In reality, I don't need the probability. I just need to calculate all possible outcomes of adding each number of one set to each number of another set. My actual sets are huge, so posting the whole thing here would be impractical.
