| Topic | Discrete Probability Distributions |
| Type | Direct probability from given distribution |
| Difficulty | Easy -2.0 This is a trivial direct reading from a probability distribution table requiring only identification that P(X > 18) = P(X = 29) = 0.1. No calculation, problem-solving, or conceptual understanding beyond basic probability notation is needed—this is purely testing whether students can read a table. |

---1 The discrete random variable $X$ has the following probability distribution
\begin{center}
\begin{tabular}{ | l | c | c | c | }
\hline
$x$ & - 15 & 18 & 29 \\
\hline
$\mathrm { P } ( X = x )$ & 0.2 & 0.7 & 0.1 \\
