The following set of random numbers represents 20 simulations of three daily flights from New York to Los Angeles, with 0, 1, 2, or 3 representing a
late departure and 4, 5, 6, 7, 8, or 9 representing an on-time departure. In how
many of the simulations was there an on-time departure for all three flights?
