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.
