A civics teacher asked her students to indicate whether they believed each of two headlines. One headline was false and the other was true, but the students did not know this. The probability that a student
selected at random believed the true headline was 90% and the probability that the student believed the

In this sample, are the events "believed the false headline" and "believed the true headline" mutually
