Suppose that 20% of all teenage drivers in a certain county received a citation for a moving violation within the past year. Assume in addition that 80% of those receiving such a citation attended traffic school so that the citation would not appear on their permanent driving record. Consider the chance experiment that consists of randomly selecting a teenage driver from this county.
a. One of the percentages given in the problem specifies an unconditional probability, and the other percentage specifies a conditional probability. Which one is the conditional probability, and how can you tell?
b. Suppose that two events E and F are defined as follows: E = selected driver attended traffic school F = selected driver received such a citation Use probability notation to translate the given information into two probability statements of the form P(____) = probability value.
