Example 1 By comparing with the exact probabilities P(X≥2)=0.5. P(X≥3)=0.25. P(X≥4)=0. We see that the bounds provided by the Markov inequality can be quite loose. 5Example 1 • By comparing with the exact probabilities 𝑃 𝑋 ≥ 2 = 0.5. 𝑃 𝑋 ≥ 3 = 0.25. 𝑃 𝑋 ≥ 4 = 0. • We see that the bounds provided by the Markov inequality can be quite loose. 5
