The odds in favor of 1 to 9 mean that there is one chance for the event to occur and nine chances for it not to occur. The probability can be found by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, there is one favorable outcome and ten total outcomes (one for the event occurring and nine for it not occurring), so the probability is 1/10 or 0.1. Therefore, the best choice is B, which gives the probability as 1/10.
