If (x − 3) is a factor of f(x), which of the following must be true? A) f(3) = 0
B) f(−3) = 0
C) ( x+ 3) is also a factor
D) There are 3 factors

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.
