The odds against an event are calculated as the ratio of the number of ways the event won't happen to the number of ways it can happen. In this case, the odds against rain are:
(Number of ways it won't rain) : (Number of ways it can rain)
= (100% - 17%) : 17%
= 83% : 17%
Therefore, the answer is B) 83 : 17.
