ESL students and plagiarism. Refer to the Journal of Education and Human Development (Vol. 3, 2009) investigation of plagiarism among English-as-a-second-language

(ESL) students, Exercise 3.30

(p. 159). Recall that of six ESL students taking a master’s course in linguistics, three admitted to plagiarizing on an essay. Two of these six students will be selected to write an original article for the college newspaper. If the two students are selected at random, what is the probability that at least one plagiarized on the essay?
