Assume that on a typical Saturday evening, 5% of all drivers are intoxicated, and the probability that an intoxicated driver is involved in a car accident is 0.2.
Assume that on a typical Saturday evening, 5% of all drivers are intoxicated, and the probability that an intoxicated driver is involved in a car accident is 0.2. Police estimate that of all car trips on a Saturday evening end with an accident. (Please note 2% = 0.02) a. The number 0.2 corresponds to which probability? (A) Pr[car accident and intoxicated] (B) Pr[car accident or intoxicated] (C) Pr[car accidentſintoxicated] (D) Pr[car accident and not intoxicated] (E) Pr[intoxicated car accident] b.

With probability 0.6, the present was hidden by mom; with
probability 0.4, it was hidden by dad. When mom hides the present,
she hides it upstairs 70 percent of the time and downstairs 30
percent of the time. Dad is equally likely to hide it upstairs or
downstairs. Given that it is downstairs, what is the probability it
was hidden by dad?

Problem 16-05 (Algorithmic)
A major traffic problem in the Greater Cincinnati area involves
traffic attempting to cross the Ohio River from Cincinnati to
Kentucky using Interstate 75. Let us assume that the probability of
no traffic delay in one period, given no traffic delay in the
preceding period, is 0.9 and that the probability of finding a
traffic delay in one period, given a delay in the preceding period,
is 0.75. Traffic is classified as having either a delay or...
