\(\frac{10}{13}\)

Find the odds in favor of events with the given probabilities. Give your answer as a ratio of whole numbers. If neither of those two numbers is 1 , also give an answer as a ratio involving both 1 and a number greater than or equal to 1 (for example, the odds 5:2 and 3:8 can be reduced to \(2.5: 1\) and 1:2.67).
