10. (1994 American High School Mathematics Examination) The probability of getting a sum of 1994 when rolling a regular die $n$ times is greater than 0, and is equal to the probability of getting a sum of $S$, then the minimum value of $S$ is ( ).
A. 333
B. 334
C. 337
D. 339
E. 341
10. B. Reason: Since $1994=6 \times 332+2$, this means: rolling 333 times and getting 332 sixes and one 2 is the scenario with the fewest rolls, and the probability of this happening is clearly not 0.

Rolling 333 times and getting 332 sixes and one 2 has the same probability as getting 332 ones and one 2, and in this case, the minimum sum of the points is: $1 \times 332+2=334$.
Therefore, the minimum value of $S$ is 334.
