Matching

Match the correct word to the corresponding blank! 1: A phenomenon is [BLANK] if individual outcomes are uncertain but there is a regular distribution of outcomes in a large number of repetitions. 2: Two events are [BLANK] if the outcome of one trial does not influence or change the outcome of any other trial. 3: Two events are [BLANK] if they have no outcomes in common and can never happen together.

Options

A.random

B.disjoint

C.independent

Step-by-Step Analysis

Let's parse the matching task carefully and then evaluate each candidate word in its appropriate blank. Blank 1: 'A phenomenon is [BLANK] if individual outcomes are uncertain but there is a regular distribution of outcomes in a large number of repetitions.' - random: This is the correct concept. When outcomes are uncertain for a single trial but show a stable distribution over many trials, we describe the process as random. The long-run regularity of outcomes across repetitions reflects randomness with a predictable distribution (e.g., normal, binomial, etc.). - disjoint: Not suitable here. 'Disjoint' describes events with no outcomes in common, which is about relations......Login to view full explanation
