Hello, hscott4!
Do you mean "odds" . . . or "probability"?
They are two different concepts.
What are the odds in favour of:
a) getting a number greater than 1 when a number cube labelled 1 to 6 is rolled.
There are six possible outcomes: .$\displaystyle \{1,2,3,4,5,6\}$ . . . all equally likely.
There are five outcomes greater than 1: .$\displaystyle \{2,3,4,5,6\}$
The probability of a number greater than 1 is: .$\displaystyle {\color{blue}\frac{5}{6}}$
The odds in favor of a number greater than 1 is .$\displaystyle {\color{blue}5:1}$
