The 2000 Census identified the ethnic breakdown of the state of California to be approximately as follows: White:46％, Latino:32\%, Asian:11\%, Blcak:7\%,and Other:4\%.~Assuming that these are mutually exclusive categories (this is not a realistic assumption), what is the probability that a randomly selected person from the state of California is of Asian or Latino descent?

The correct answer is(d). Because ethnic group categories are assumed to be mutually exclusive, P(Asian or Latino)=P(Asian)+P(Latino)=32\%+11\%=43\%
