According to Google, the three most common error codes from visiting a web site are
403
,
404
, and
500
.
- Without knowing which error code is most common, express this set mathematically.
- Error code
500
is the most common. Error code 403
is the least common of these three. And that leaves 404
in the middle. Express the error codes in a mathematical way that appreciates how frequently they happen, from most often to least often.
- Since we only have to describe a collection of three numbers and their order doesn’t matter, we can write {403,404,500}.
- Now we must describe the same three numbers and we want readers to know that the order we are writing the numbers matters. We can write (500,404,403).
