A value like 1/99, or about 1.01%, can describe a rare chance, such as a prize winning on a game show or a defect in a large batch of products. It means the event happens only occasionally, not that it is impossible.

To picture it, imagine one marked item among about 100 items in a row. That gives a quick sense of how small the share is, even if the exact amount is a little over one out of 100.

A common mix-up is treating 1/99 as exactly 1% because it is close. It is slightly larger, so repeated estimates or comparisons may be a bit off if you round it too soon.
