 							  Suppose that E was repeated n times under similar conditions.
 							  Let fn (A) be the times that A occurs. The ration
 							  $$Fn (A) =
-							  fn (A) /
-							  n$$
+							  \frac{ fn (A)}{n}$$
 							  is said to be the frequency of event A in the n trials. If n is
 							  large enough, the probability of event A will be approximated
 							  by Fn (A).
