Data on 450 candidates who took an examination in social science, mathematics, and science. Passed in all subjects: 167. Failed in all subjects: 60. Failed in social science: 175. Failed in mathematics: 199. Failed in science: 191. Passed in social science only: 62. Passed in mathematics only: 48. Passed in science only: 52. How many failed in social science only? How many failed in one subject only? How many passed in mathematics and at least one more subject? How many failed in two subjects only? How many passed at least in one subject?
