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. three-tenths two over five nine over twenty eleven over twenty

Saul Le · Answer 1

First, we need to have a random number table.

Next, we randomly choose numbers from the table and consider the first five digits.

After, the corresponding flight arrival is determined based on the given rules in the problem.

Then, the probability that at least 2 will arrive late is determined by taking the average.
