2. The Drake Equation:

(a) What, exactly, does the Drake Equation estimate?

(b) If you are like Frank Drake or Carl Sagan, you are an optimist who believes that the development of life, intelligence, and technological civilizations are not "vanishingly small", but are typical. That is, that what happened on earth is not rare. Explain them why Drake and Sagan would say that "N=L" is a good approximation to the Drake Equation.
