That depends on the subject. People are not as fallible on life or death subjects or more people would accidentally walk in front of cars, trains or fall of high places. Anybody have an idea what that probability would be?
People are pretty fallible in these cases, too, literally. Look at the number of fatalities in canyons with well marked paths and fences.
For each encounter with a precipice, I would strongly guess the success probably is > 99.999.
