All Newsweek (March 20. 2011) They\'re the sort of scores that drive high-school history
teachers to drink. When NEWSWEEK recently asked 1,000 U S. citizens to take America\'s
official citizenship test 30 percent couldn\'t name the vice president Seventy-five percent
couldn\'t correctly say why we fought the Cold War forty-five percent were unable to define the
Bill of Rights. And 6 percent couldn\'t even circle Independence Day on a calendar. Don\'t get us
wrong: civic ignorance is nothing new. For as long as they\'ve existed. Americans have been
misunderstanding checks and balances and misidentifying their senators. And they\'ve been
lamenting the philistinism of their peers ever since pollsters started publishing these dispiriting
surveys back in Harry Truman\'s day. (He was a president, by the way) According to a study by
Michael X. Delli Carpini, dean of the Annenherg School for Communication, the yearly shifts in
civic knowledge since World War II have averaged out to \"slightly under I percent.\" In a
sample of 10 individuals, what is the probability 4 arc could not name the vice president? In a
sample of 12 individuals what is the probability at least 8 arc not able to correctly say why we
fought the Cold War? In a sample of 15 individuals, what is the probability no more than 10 are
unable to define the Bill of Rights? In a sample of 9 individuals, what is the probability that 2, 3,
4, or 5 could not circle Independence Day on a calendar?
Solution.
