Final answer:
To find the probability of an event occurring in a given range, you need to integrate the probability function over that range.
Step-by-step explanation:
To find P(0 < x < 12), we need to integrate the given probability function f(x) over the interval 0 ≤ x ≤ 12. Since the function is restricted to this interval, the probability of the event occurring in this range is equal to the integral of the function over that range. Therefore, P(0 < x < 12) can be found by evaluating ∫012 f(x) dx.
