[Steps Shown] A random variable X follows a distribution with probability density function f_X(x)=k e^-x, 0 ≤q x Determine the value of k. (6 points)


Question: A random variable \(X\) follows a distribution with probability density function

\[f_{X}(x)=k e^{-x}, \quad 0 \leq x<\infty .\]
  1. Determine the value of \(k\). (6 points)
  2. Calculate the cumulative density function \((\mathrm{cdf}), F(0.2) .(6\) points)
  3. A median of a distribution is defined as a value m such that \(\int_{-\infty}^{m} f_{X}(x) d x=\int_{m}^{-\infty} f_{X}(x) d x=1 / 2\). Find the median of \(X\).
