In CBC's poll tracker, why do the probabilities of winning not add up to 100%?
In CBC's poll tracker at: https://newsinteractives.cbc.ca/elections/poll-tracker/canada/, probabilities of winning the 2019 Canadian federal election are provided.
Currently, these are 11% Liberal majority, 39% Liberal minority, 42% Conservative minority, and 6% Conservative majority. By my count, these probabilities add up to 98%. Shouldn't this be 100%?
