When an individual believes that the odds of an event occurring increase if the event hasn’t occurred recently. Please select the best answer from the choices provided A B C D

Answer 1

Confirmation bias is described by choice A. This occurs when a person already has a preconceived notion about what the result should be, and biases his investigations to only explore things that would support that conclusion. This is dangerous because it does not leave room for changing of opinions.
Choices B and C are more logical ways to approach an experiment.
Choice D is another fallacy, but this is statistical bias (the gambler's fallacy) rather than confirmation bias.
