Again im not the best at geometry what is the equation for the line of reflection that maps the trapezoid onto itself? a. x = 0 b. x = 3 c. y = 3 d. y = 0 pic of graph

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18 }, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. 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.
