In this question, we given a piece-wise function, that has different definitions depending on the domain.
Evaluate the function at x = 0.
The exercise asks for us to evaluate the function at 
We have to look at the definition, and see which definition includes  . The equal sign at
. The equal sign at  is on the second definition, that is:
 is on the second definition, that is:

Thus, at  , the value of the function is 1, and the correct answer is given by option A.
, the value of the function is 1, and the correct answer is given by option A.

Answer:
1 on 3
Step-by-step explanation:
The red dice has 6 faces. The number you have to obtain is less than 3. So your answers must be 1 and 2. The numbers 1 and 2 are two solutions out of six. Now the same goes with the white dice. Two solutions out of six. You combine them and obtain 4 on 12. Then, you reduce the answer in minimal terms and finally obtain 1 on 3.
