Before matching, note the left-hand prompts describe statistical concepts, and the right-hand options provide possible terms. Option consideration 1: The phrase 'The probability of A' corresponds to a symbol for the probability of event A. Among the right-hand terms, 'P(A)' is the notation for the probability of A, so this mapping fits logically. Option consideration 2: 'This summarizes the relationship between two variables' points to a summary of how two variables relate. A contingency table is a common tool used to summarize and display the relationship between two categorical variables, showing counts or frequencies of joint occurrences. Other options do not capture ......Login to view full explanation
