1. The problem is to understand and interpret the inequality $X \geq 0$. 2. This inequality states that the variable $X$ is greater than or equal to zero. 3. It means that $X$ can be zero or any positive number but not negative. 4. On a number line, this represents all values starting from zero going to the right (positive direction) inclusive of zero. 5. This kind of inequality is common in domains where negative values are not possible (like lengths, counts, probabilities). Final conclusion: $X$ is any real number such that $X \geq 0$.
