Quota Problem: Archaeology An archaeological excavation at Burnt Mesa Pueblo showed that about 10% of the flaked stone objects were finished arrow points (Source: Bandelier Archaeological Excavation Project: Summer 1990 Excavations at Burnt Mesa Pueblo, edited by Kohler, Washington State University). 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 12P(0) $ 0.90, or P(0) # 0.10.
