| Topic | Uniform Distribution |
| Type | Calculate basic probabilities |
| Difficulty | Easy -2.0 This is a trivial probability calculation requiring only counting outcomes (4,5,6,7 = 4 values) and multiplying by 0.1 to get 0.4. It tests basic understanding of discrete uniform distributions with no problem-solving required, making it significantly easier than average A-level questions. |

---2 The discrete random variable $X$ has probability distribution defined by
$$\mathrm { P } ( X = x ) = \begin{cases} 0.1 & x = 0,1,2,3,4,5,6,7,8,9 \\ 0 & \text { otherwise } \end{cases}$$
Find the value of $\mathrm { P } ( 4 \leq X \leq 7 )$\\
Circle your answer.
