Philosopher: An event is intentional if it is a human action performed on the basis of a specific motivation
An event is random if it is not performed on the basis of a specific motivation and it is not explainable by normal physical processes
Yasuko continued to breathe regularly throughout the time that she was asleep. This was a human action, but it was not performed on the basis of a specific motivation. Ttherefore, her breathing was a random event.
