“Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated, can long endure.…It is for us, the living…to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced.

But we must feed our Army first – if we can do so much as that. Our captives need not starve if Lincoln would consent to exchange prisoner; but men are nothing to the United States – things to throw away. If they send our men back they strengthen our army, and so again their policy is to keep everybody and everything here in order to starve us out.

This is the same example we did in class about the relationship between pairwise independence, and independence of three or more events. Consider the experiment of two independent fair coin tosses. This experiment has 4 elements in its sample space: {HH, HT, TH, TT}.  Let A={HH, HT} be the event that the first toss is H. Let B={HH, TH} be the event that the second toss is H. Let C={HH, TT} be the event that both tosses are equal. Which of the following statements is incorrect?
