The large counts condition can be expressed as np ≥ 10 and n (1-p) ≥ 10, where n is the sample size and p is the sample proportion. This means that both the number of successes (np) and the number of failures (n (1-p)) in the sample should be at least 10.AP stats vocab: 74 terms. atourville32. Preview.
