A die is rolled 600 times and gives a six 180 times. What can you conclude?

  1. The expected number of sixes was 180
  2. The die is fair
  3. The die may be biased, because about 100 sixes were expected
  4. Sixes are less likely than other numbers
Answer

C) The die may be biased, because about 100 sixes were expected

For a fair die, 600 16 = 100; 180 is far more than expected. SLO M-09-C-08 · Application
