Question

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? 459 981 317 444 432 858 194 192 639 709 742 626 702 258 955 880 505 804 771 132

Answer 1

We need to find the simulations which don't have any 0, 1, 2, or 3. These simulations are: 459 444 858 955. Then, the number of simulations there was an on-time departure for all three flights is 4.
