Assume the likelihood that any flight on Northwest Airline arrives within 15 minutes of the schedule time is .90. We selected four flights from yesterday top study.
a. What is the likelihood all four flights arrived within 15 minutes of the schedule time?

Ans: 0.9^4 = 0.6561
--------------------------------
b. What is the likelihood that none of the selected flights arrived within 15 minutes of the schedule time?
---
Ans: 0.1^4 = 0.0001
------------------------------
c. What is the likelihood at least one of the selected flights did not arrive within 15 minutes of the schedule time?
---
P(at least one did not) = P(at least one was late)= 1-P(none were late)
= 1 - 0.6561 = 0.3439
