Refer to University of New Mexico professor Jane Hood's study of the fieldwork methods used by qualitative sociologists, presented in Exercise 2.195 (p. 108). Recall that she discovered that fieldwork methods could be classified into four distinct categories: Interview, Observation plus Participation, Observation Only, and Grounded Theory. The table that follows, reproduced from Teaching Sociology (July 2006), gives the number of sociology field research papers in each category. Suppose we randomly select one of these research papers and determine the method used. Find the probability that the method used is either Interview or Grounded Theory.
Fieldwork Method.....................................Number of Papers
Interview.................................................. 5,079
Observation plus Participation......................... 1,042
Observation Only........................................ 848
Grounded Theory......................... ...............537
