How many calculators do I need to have seen in order to make the claim that there are many calculators which are essentially 100% reliable?
Note that I am referring to actual physical calculators, not calculator apps on computers.
Well, to make the claim you actually made, which is that you haven't seen a single calculator that was wrong, anywhere from zero to all of them. It's just that the "zero" end of that spectrum doesn't really tell us anything about calculators.
When was the last time you saw an actual calculator (not an app) give a wrong (not merely rounded) answer?
