"Odd" in Math

In the world of mathematics, "odd" has very specific meanings.

Odd Numbers

An integer (a whole number) is called odd if you can't divide it exactly by two. If you try to divide an odd number by two, you'll always have a remainder. For example, 1, 3, 5, 7, and 9 are all odd numbers. This is part of a math idea called even and odd numbers.

Odds in Probability

In probability theory, which is about how likely things are to happen, "odds" are a way to show how probable an event is. The odds in favor of something happening compare the chance of it happening to the chance of it not happening. For example, if the odds of winning a game are 1 to 2, it means for every 1 time you might win, you might lose 2 times.
