= Solution

The <strong law of large numbers> states that, for <independent and identically distributed random variables> $X_1,X_2,\ldots$ with $\mathbb E|X_1|<\infty$,
$$
\boxed{\frac1n\sum_{j=1}^nX_j\longrightarrow\mathbb E X_1\quad\text{almost surely}.}
$$
Thus, outside an event of <probability> zero, the <sample mean> converges to the common <expected value>.
