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? 339 931 317 444 432 858 194 192 649 709 742 626 702 258 955 880 505 854 774 132
