On-Time Airplane Arrivals. The greater Cincinnati airport led major U.S. airports in on-time arrivals in the last quarter of 2005 with an 84.3% on-time rate. choose 5 arrivals at random and find the probability that at least 1 was not on time.

\n" ); document.write( "-------------------
\n" ); document.write( "P(1<= not on time <=5) = 1 - P(x = 0 not on time)
