The 2000 census allowed each person to choose from a long list of races. That is, in the eyes of the Census Bureau, you belong to whatever race you say you belong to. If we choose a resident of the United States at random,. The 2000 census gives these probabilities:
  

Hispanic

Not-Hispanic
 
Asian

0.000

0.036
 
Black

0.003

0.121
 
White

0.060

0.691
 
Other

0.062

0.027
Let A be the event that a randomly chosen American identifies himself/herself as Hispanic. Let B be the event that the person identifies as white.
a)      Verify that the table gives a legitimate assignment of probabilities.
b)      What is P(A)
c)       Describe Bc in words and find P(Bc)
d)      Express “the person chosen is a non-Hispanic white” in terms of events A and B. What is the probability of this event?
