Roughly, speaking, we can use probability density functions to model the likelihood of an event occurring. Formally, a probability density function on (-0, 00) is a function f such that f (x) > 0 and roo | f(x) = 1. (a) Determine which of the following functions are probability density functions on the (-∞, 00). 0 < x < e (i) f(x) = otherwise -2 0 < x < 2/2 (ii) ƒ(x) = (x – v2)3 otherwise Aeda 0< x < ∞ (iii) f(x) = otherwise where A> 0
