Suppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30% arrive late. Valerie used the random-number table to find the experimental probability that of 5 flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1, 2, 3, 4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving late.

You have a hundred digits in that chart. Count the number of sevens, eights and nines and you will have the experimental probability.

@Stacey can you tell me the answer

stacey · Answer

If you can count the sevens, eights and nines and tell my what you get, then I can tell you the answer.

stacey · Answer

The way I did it is calculate the possibility of no late flights or only one late flight. Adding those and subtracting from 1. I don't mind explaining this, but I will not do your work for you.
