Classical Probability Assessment (continued) Example 3. 3 When we roll a pair of dice, what is the probability a) b) Of getting a double? Of getting a total more than 8? Example 3. 4 What is the probability that poker player (Texas Holdʼem game) is dealt a) b) Two tens? Ace and king? Answers to both examples are available on my personal website. Classical probability assessment is not applicable if: � � The set of all elementary outcomes is infinite The set of all elementary outcomes is finite, but these outcomes are not equally likely Chapter 3: BASICS OF PROBABILITY 7
