AB and AC are opposite rays. All of the following are true except A. A is between B and C.
B. A, B, C are collinear.
C. A, B, C are coplanar.
D. AB=AC

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.
