III. guitare fingerpickingWebTo obtain an upper bound for P(X > 0), and thus a lower bound for P(X = 0), we first note that since X takes only integer values, P(X > 0) = P(X ≥ 1). Since X is non-negative we can now apply Markov's inequality to obtain P(X ≥ 1) ≤ E[X]. Combining these we have P(X > 0) ≤ E[X]; the first moment method is simply the use of this inequality. bovis nancy
