$begingroup$ As part of your responses, you requested how summing up finite items (or goods of finite issues with other finite things) can give you something infinite. This should not be far too counterintuitive; The theory is that you're summing up infinitely many of Individuals finite points. If nearly anything, It really is counterintuitive which you could at times sum up infinitely many things and obtain a finite final result. I do concur, nonetheless, that the thought of a video game such as the St. Petersburg Recreation seems counterintuitive. Element of it'd be as a result of term "expectation." In widespread utilization, after we count on something to happen, we expect It truly is a lot more likely to occur than not.
