Explanation

The order of entrees the guests chose from does not matter.

Therefore, the number of different possibilities of entrees is \(\frac{12 \times 11 \times 10}{3 \times 2 \times 1}\)=220. The order of desserts does not matter
either, so there are \(\frac{3 \times 2}{2}\)=3 possible different combinations of desserts.

Multiplying the two together gives a total of 660 possible different combinations of offerings.
