SUMMARY
The computation of $F_{X_1}(x)$ is derived from the binomial distribution's probability mass function, expressed as $F_{X_1}(x) = \displaystyle\sum_{j=1}^n \binom{n}{j} F^j(x) (1-F(x))^{n-j}$. This formula simplifies to $F_{X_1}(x) = 1 - (1 - F(x))^n$, confirming that the left-hand side equals the right-hand side. The complement rule, $P(A^c) = 1 - P(A)$, is utilized to establish the relationship between $F_{X_1}(x)$ and the cumulative distribution function.
