Unformatted text preview: arrival time of the vehicle is random, and not at all connected to the signal (in particular, the traffic signal is isolated and not synchronized with other signals that the vehicle passes) then it 10 CHAPTER 1. FOUNDATIONS seems intuitively reasonable to assign probabilities to the colors that are proportional to their dwell 2 5 1 40 8 times. Hence, we declare that P {green} = 30 = 5 , P {yellow} = 75 = 15 , and P {red} = 75 = 15 . 75 Note that the three outcomes are not equally likely. Example 1.2.3 (Standard unit-interval probability space) Take Ω = {ω : 0 ≤ ω ≤ 1}.3 Imagine an experiment in which the outcome ω is drawn from Ω with no preference towards any subset. In particular, we want the set of events F to include intervals, and the probability of an interval [a, b] with 0 ≤ a ≤ b ≤ 1 to be given by P ( [a, b] ) = b − a. (1.2) Taking a = b, we see that singleton sets {a} are events, and these sets have probability zero. In order for the event axioms to be true, open intervals (a, b) must also be events and P ( (a, b) ) = b − a. Any open subset of Ω can be expressed as the union of...
