Now look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30. And if that is met, then we check if the number of successes/ failures in a sample are more than 10.This is known as The 10% Condition. The 10% Condition: As long as the sample size is less than or equal to 10% of the population size, we can still make the assumption that Bernoulli trials are independent.
