the word "percent" is actually a combination of words "per cent"... which is "per 100". Cent, as in 1/100 of a dollar or as in the word century, for 100 years, etc. A percentage is a number that represents an expectation or a fact, in numbers "out of a hundred samples". Out of 100 people, 37 got the cold... therefore 37 per cent, or 37% fell ill. Because it is out of a hundred, x% can be written as a fraction, x/100 or decimal. The term percent, the symbol %, is just a unit that represents a fractional portion. We use percentages as statements of fact, like the example of people getting the cold I used. We also use percentage as an expectation, or probability, if we can calculate what the factual percentage will be after the fact with any certainty.

In statistics, the highest probability is 1 or 100 percent. Percent is the most useful way to transmit stat information.

statistics/probabilistics is a subject that takes events that happened before like... if a you're trying to bet on a team and the team u're betting on won 3 out of 4 games it played it will have a 75% chance of winning(the probability) though this is a weird assumption because there are more factors leading to the final % of a team because you have to take in mind factors like weather, the % of the other team etc... so % are used to know what is the probability of something happening

We use percentages because when we are trying to the probability of things we like to know the percentage chances..
