1/52 = ≈1.92%
Rounded to 2 decimal places.
A value like 1/52 can show up when something happens once during each week of a year, since there are about 52 weeks. For example, a weekly event makes up roughly 1.92% of the year.
To picture 1/52 quickly, imagine a whole divided into 52 equal pieces and focus on just one tiny piece. It is close to 2%, so you can estimate it as about 2 out of every 100.
A common point of confusion is thinking that 1/52 means exactly 2%, when it is slightly smaller than that. It also does not mean one out of every 52 people will always experience something, because real-life results can vary.
