Step 1


The\text{ probability of choosing a red marble = }(1)/(9)

Step 2:

Total number of outcomes = 9

Number of outcomes we want = 1

Number of outcomes we don't want = 9 - 1 = 8

Step 3


\begin{gathered} \text{Odds in favor = }\frac{wanted\text{ }outcomes}{\text{unwanted outcomes}} \\ \text{Odds in favor = }(1)/(8)\text{ or 1 : 8} \end{gathered}

Final answer

Odds in favor = 1 : 8 or 1/8
