n 2000, 86% of all Caucasians in the United States, 77% of all African-Americans, 77% of all Hispanics, and 85% of residents not classified into one of these groups used the Internet for e-mail. At that time, the U.S. population was 69% Caucasian, 12% African-American, and 13% Hispanic. What is the probability that at that time a randomly chosen U.S. resident used Internet for e-mail?
