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={6,7,8,9,10,11} and event G={10,11,12,13}. 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.
