finite math

A probability experiment was conducted in which the sample space of the experiment is S={1,2,3,4,5,6,7,8,9,10,11,12}, event F= {3,6,7,}, and event G={9,10,12}. Assume that each outcome is equally likely. List the outcomes of F and G. find P(F or G) by counting the number of outcomes. Determine P(F or G) using the general addition rule.
