Answer:
To find the odds in favor of Cody being first, we need to divide the probability of him winning (25%) by the probability of him not winning (75%).
Odds in favor of Cody winning = 25% / (100% - 25%) = 25% / 75%
Simplifying, we get:
Odds in favor of Cody winning = 1/3
Therefore, the odds in favor of Cody being first in the 50m backstroke are 1 to 2 (or 1:2).
