Determine probability of random sample
WebAssuming that A and B are events with nonzero probabilities, P (A B) = P (A) is actually mathematically equivalent to P (B A) = P (B). We can see this because P (A B) = P (A) means P (A and B)/P (B) = P (A) from definition of conditional probability, P (B A) = P (B) means P (A and B)/P (A) = P (B) from definition of conditional probability, and WebHis team takes a random sample of stores to determine if the research hypothesis that the average number of employees per store is greater than 200 is true.
