4. Bus (6 - 11 grades, $\mathbf{1}$ point). Anya is waiting for a bus. Which event has the highest probability

\[
\begin{gathered}
A=\{\text { Anya waits for the bus for no less than one minute }\} \\
B=\{\text { Anya waits for the bus for no less than two minutes. }\} \\
C=\{\text { Anya waits for the bus for no less than five minutes. }\}
\end{gathered}
\]

From the diagram, it is clear that event $A$ includes event $B$, and event $B$ includes event $C$, meaning that event $A$ is the most extensive:

$$
C \subset B \subset A
$$

Therefore,

$$
\mathrm{P}(C) \leq \mathrm{P}(B) \leq \mathrm{P}(A)
$$

Answer: The most probable event is $A$.
