Ivan · Answer 1

Answer: Insensitivity to prior probabilities.

Explanation: In a bid to make inference based on a given data or information, people may tend to base their conclusion on representativeness. In the scenario above, I concluded that half of the students in my class of 200 are in a fraternity or sorority. However, the baseline probability was that 20% of students in the university belong to a fraternity or sorority. Here, I have used the baseline probability to make inference or guess the probability that students who wore shirt with Greek letters on them belonged to fraternities or sororities even though no description was given about students in my class.
