What is the probability of a seredipitous encounter with a friend? Imagine you live in a university with 12000 people. You are new to campus and only know 50 people (on a first name basis). What are the chances that you run into at exactly one person you know if you see 250 distinct people from the population? Assume that seeing each person from the population is equally likely. Provide your answer to three decimal places.

Note - 0.328 is incorrect
