For any random variable and any positive real number & > 0,Markov's in- equality states that: P{IX| > &}

For any random variable and any positive real number E > 0,Markov's in- equality states that: P {IXI > E} LE(IXI). Prove Markov's inequality. You may assume that X is a continuous random variable with pdf fx. (Hint: adopt the proof of Chebyshev's inequality.)
