The following set of random numbers represents 20 simulations of 3 daily flights from philadelphia to seattle, with 0, 1, 2, or 3 representing a late departure and 4, 5, 6, 7, 8, or 9 representing an on-time departure. how many of the simulations was there an on-time departure for all 3 flights? 506 619 535 769 096 380 527 555 737 192 092 658 694 320 442 812 968 763 374 282 a. 4 b. 3 c. 5 d. 6

we have three flights names as 0,1,2 and 3.

we have the codes of flights departing on time (7,8 and 9) .

we have given the set of codes given below we need to choose code flights departed on time.so we need to have number on our code must be 0,1,2,3,7,8 and 9.

from the set of codes given matching codes for on time departed flights are 737,092,380,812,

so four can be selected as on time departed .

here we have 320 we cannot choose this as on time departure because it does not contain 7,8 and 9 in it

you can't solve x because it is 2 linear equation and you only have one equation
