Question

3. If a random variable has the probability density $f(x) = \begin{cases} 2e^{-2x} & \text{for } x > 0\\ 0 & \text{for } x \le 0 \end{cases}$ Find the probability that it will take on a value between 0.5 and 1.

          3. If a random variable has the probability density
$f(x) = \begin{cases} 2e^{-2x} & \text{for } x > 0\\ 0 & \text{for } x \le 0 \end{cases}$
Find the probability that it will take on a value between 0.5 and 1.
