Arectangle that is 2 inches by 3 inches has been scaled by a factor of 7.what are the side length of the scaled copy suppose you want to size copy back to its original size. what scale factor should you use

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.
