Solution: The total number of ways to choose 4 modules from 12 is $\binom124$. The number of favorable outcomes (2 non-compliant and 2 compliant) is $\binom32 \cdot \binom92$. Thus, the probability is $\frac\binom32 \cdot \binom92\binom124 = \frac3 \cdot 36495 = \frac108495 = \frac1255$. \boxed\dfrac1255 - Appfinity Technologies
