Suppose flights at a large metropolitan airport are on-time 68% of the time and late 32% of the time. We want to use a table of random digits to simulate flight status (on-time or late), so we'll assign 01, 02, … , 68 to represent on-time flights, and 69, 70, … , 99, 00 to represent late flights.
Use the information above and these random digits to simulate 20 flights at this airport:

How many of the simulated flights were on-time?
A) 19
B) 15
C) 11
D) 10
E) 9
