Answer:
<em>120 different menus can be selected</em>
Step-by-step explanation:
<u>Variations</u>
The catered menu will include a soup (S), a main course (M), a dessert (D), and a beverage (B).
Since there are 4 soups, 5 main courses, 3 desserts, and 2 beverages, one can think of any combination of a general pattern like S-M-D-B. Each place of this pattern can be used in 4,5,3, and 2 ways.
Thus, the total possible variations of the menu are 4*5*3*2= 120.
