An archaeological excavation at burnt mesa pueblo showed that about 10% of the flaked stone objects were finished arrow points†. how many flaked stone objects need to be found to be 90% sure that at least one is a finished arrow point? (hint: use a calculator and note that p(r ≥ 1) ≥ 0.90 is equivalent to 1 − p(0) ≥ 0.90, or p(0) ≤ 0.10.) objects
