Use the given transformation to evaluate the integral. double integral (4x+8y)dA, where R is the parallelogram with vertices (-1,3), (1,-3), (3,-1) and (1,5); x=1/4(u+v), y=1/4(v-3u)

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.
