What is the perimeter of the trapezoid with vertices q(8, 8), r(14, 16), s(20, 16), and t(22, 8)? round to the nearest hundredth, if necessary.

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.
