Congruence of percentage of chosen attribute levels and Probabilty from respective utility

In a CBC survey, participants choose in total 2724 times level A and 2487 times level B (=52.3% A and 47.7% B).

The average utility in CBC/HB for A was -.02618144 and for B  = .16109872.

Calculating the odds and thereafter the probabilities results in 49.3% for A and 54.0% for B.

Is this plausible? Is there literature on this effect?

I am not following your math.  Where do the 49.3% and 54.0% come from and why do they not sum to 100%?
