You randomly throw 200 darts at a dartboard (the probability of hitting any spot on the dartboard is uniform). The dartboard has two types of regions: red and black. 57 of the darts you threw hit a red region. Approximately what percentage of the dartboard is black?
  • (200-57)/200 = 71.5%. Alternatively, we can add a pseudocount of one to each class to get: (202-58)/202 = 71.28%.
