A probability experiment is conducted in which the sample space of the experiment is S = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}. Event F = {8, 9, 10, 11, 12}, and event G = {12, 13, 14, 15}. Assume that each outcome is equally likely. List the outcomes in F or G. Find P(F or G) by counting the number of outcomes in F or G. Determine P(F or G) using the general addition rule.
