The image contains the following mathematical text and request:

---

Let \( Y_1 < Y_2 < Y_3 < Y_4 \) be the order statistics of a random sample of size 4 from the distribution having pdf

\[ f(x) = e^{-x}, \, x > 0 \]

zero elsewhere. Find \( E(Y_1) \).

---

This problem involves finding the expected value of the smallest order statistic (\(Y_1\)) from a sample of size 4, drawn from an exponential distribution with the probability density function \( f(x) = e^{-x} \) for \( x > 0 \).
