probability A. measures the likelihood that the event occurs based on the actual results of the experiment; vevent P(event) = (number of times the event occurs) = (number of times the experiment is done) sample space B. vexperimental probability If two events are independent, what is the probability that both events occur? A) zero A AnB B B) one C) the sum of their probabilities the elements that are common to two or more sets D) the product of their probabilities E) the difference in their probabilities C. Anser D intersection (sets) D. same probability of occurring theoretical probability E. union (sets) equally likely v null (empty) set two way table random choice the combination of all elements from two or more sets F. a measure of the likelihood that an event will occur G. a single outcome or a group of outcomes H. set of all possible outcomes of an experiment I. a choice made without a reason J. a set with no elements K. the likelihood of an event based on mathematical reasoning L. a table with columns and rows recording the number of items belonging to different categories
