I'm currently gathering data points on sports betting. Each bet is small, only around $5. Depending on the odds that I get each bet will result in +$5~ or -\$5~. For example, a 5 bet sample set could be +5, +5.35, +5.8, -5.15, -5.4. That's just an example. I'm interested in the sum of these numbers. In this example, the sum is +5.6.
