To solve this problem, it is necessary to use the multiplication counting rule. It states that the total outcomes of two events a and b is the product of a and b, it means a*b.
In this case, the total outcomes is the product of the number of options for each event (sandwiches, fruits and drinks). This is 3*4*2.
