The number of simulations in which was there was an on-time departure for all three flights is; 6
How to carry out number simulations?
We are given;
Number of Simulations = 20
Numbers that represent late departure = 0, 1, 2 or 3
Numbers that represent On-time departure = 4, 5, 6, 7, 8 or 9.
Now, the 20 simulations as seen online are;
339 931 317 444 432 858 194 192 649 709
742 626 702 258 955 880 505 854 774 132
To know the number of simulations that were on-time departure, we need to find the ones that don't include 0, 1, 2 or 3.
Looking at the simulations, the ones that represent on-time departure are 444, 858, 649, 955, 854, 774.
Thus, there are 6 simulations in which was there an on-time departure for all three flights
