4. Three Rolls (from 6th grade. 1 point). A die is rolled three times. Which event is more likely:

$A$ "some number of points will fall at least twice" or

$B$ "three different numbers of points will fall on three rolls."
Solution. The probability of event $B$ is

$$
\frac{6 \cdot 5 \cdot 4}{6^{3}}=\frac{5}{9}>\frac{1}{2}
$$

Therefore, event $B$ is more likely than event $A=\bar{B}$.

Answer: $B$.
