358/359 = ≈99.72%
Rounded to 2 decimal places.
A value like 358/359, or about 99.72%, can describe something that is almost always successful. For example, a website might load correctly 358 out of 359 times, or a factory might produce 358 working items out of every 359.
To picture it quickly, imagine a group of 359 dots with only one dot missing or marked differently. It is just a little less than 100%, so you can think of it as “nearly all” rather than exactly all.
A common mistake is to treat 99.72% as if it means nothing ever went wrong. Even a tiny fraction left over matters when the total number of attempts is very large, so a rate this high can still include many failures in real life.
