The total possible outcomes of a serving would be 16.
Explanation:
Given that,
The total number of beverages = b = 4 ( water, milk, juice,
or tea)
Ice options = i = 2 (with or without ice)
Serving options = s = 2 (glass or plastic cup)
We have to find the total possible outcome x, that can be calculated using
x = b x i x s
Putting the values in the equation, we get
x = 4 x 2 x 2
x = 16
Hence, the total possible outcomes of a serving would be 16.
