for every a and b, then X is called a continuous random variable and fX is called its density function (or probability density function, or just pdf). Wherever fX is continuous, it is equal to the derivative of FX. Note that if X is continuous, the probability of any single value of X is zero: FX(a-) = FX(a) for every a, so P(X=a) = 0 for every ... ................
