My example indicates that the log odds for A is +1.16 and T is -0.22. I am not able to duplicate this result. Can you explain the steps calculate the log odds from these probabilities?

Thank you.

The funny part is that I am good at individual subjects like Probability by itself or logs by itself So who was the genius who came up with log odds?
