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 3

Look at the random number table

The first block is this set of numbers

65926

it tells us that "The digits 7, 8, and 9 represent flights arriving late."

The digits "6", "5", "2" and "6" are on time arrivals

the only late flight is the one "9" that pops up in the middle

So in the first block of 5 flights, there is only one late arrival

Answer 4

move to the next block in the same row (row 1)

31459

how many late arrivals are there in this set of digits?
