document.write( "Question 1204187: Suppose a study of the faculty at U.S. medical schools revealed that 33% of the faculty were women and 67% were men. Of the female faculty, 33% were full/associate professors, 49% were assistant professors, and 18% were instructors. Of the male faculty, 51% were full/associate professors, 36% were assistant professors, and 13% were instructors. If a faculty member at a U.S. medical school selected at random held the rank of full/associate professor, what is the probability that the faculty member was female? (Round your answer to two decimal places.) \n" ); document.write( "
