A) sum rule
B) product rule
C) chi square test
D) binomial expansion
E) random sampling error

Question

Quizplus · Accepted Answer

The product rule is used to determine the probability of two or more independent events occurring in sequence. In this case, the events in question are independent and occur in order, so the product rule would be the best choice for determining their probability. The sum rule is used to determine the probability of either one event or another occurring, not the probability of multiple events occurring in sequence. The chi-square test is a statistical test used to assess the goodness-of-fit of observed data to expected data. The binomial expansion is a mathematical formula used to expand binomial expressions, not to determine probabilities. Random sampling error refers to the extent to which random fluctuations in sample data affect the accuracy of estimates made from that sample, which is not relevant to determining the probability of three independent events in order.
