Question

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. Find the experimental probability that of 5 flights, at least 2 will arrive late.

Answer 1

This is an experimental probability project.

Ideally you will need a 10-sided die (can get from toy/game stores) in the shape of a duodecahedron (10 identical faces), and proceed as described.

The more trials you make, the closer it should approach the expected values, i.e. 10% early, 60% on time and 30% late.

Your results should include the number of trials and the results obtained.

I would start with 3-4 experiments with 10 trials, about 1 or 2 with 100 trials.

If you are familiar with random number tables or programming, you can do it on the computer as well.
