Final answer:
The given question lacks sufficient information to definitively complete the calculation of (6) + f(-2) + f(2) as the piecewise function f(x) is not provided.
Step-by-step explanation:
The question you're asking involves evaluating a piecewise defined function f(x). Although the function itself isn't explicitly given, it appears to refer to evaluating and adding certain values of the function f(x). The expression we are evaluating is (6) + f(-2) + f(2). Without the explicit definitions of f(x) for various ranges of x, we cannot compute the exact values for f(-2) and f(2). The information provided doesn't contain sufficient details to accurately answer the question, including calculating the probability P(0 < x < 12) for a continuous probability function.
