    There are 5 attempts at a 1/7 chance. It's hard to see how the probability is 5/12 . . .

    Are you sure there are no other conditions, like gets only one, or there are only one of each of the seven available?

    this is the question that was right before it 3. Before leaving, Walt gets news that his competition may try to attack him. He decides to arm himself with lots of weapons before he leaves. Walt goes to his local arms dealer and randomly buys 5 weapons from a total of 7 guns and 5 rocket launchers. What is the probability that Walt buys only 2 guns? that answer was 648

    Ah, randomly buys 7 *weapons* that still includes the 5 rocket launchers. There are a total of 12 things to choose from.
