Figure 3.16 suggested that race was related to whether a male driver was searched by police in San Diego in 2016. When exploring this question, it is important to consider the cause of the traffic stop; information that is available in the data. Moving violations, equipment violation, and suspect information were some of the reasons for traffic stops. If we only consider data such that moving violations were the cause, the Table summarizes whether a male driver was searched according to his race.

a) Find the probability that aWhite male driver was searched.
b) Find the probability that a male driver was not searched.
c) Find the probability that a male driver was searched given that he was Black.
d) Find the probability that a male driver was searched given that he was White.
e) Find the probability that a male driver was searched and was Hispanic.
f) Do you think the probability of a male driver being searched during a moving violation stop is independent of race? Explain.
