The cumulative distribution function of the random variable X is defined by F(x) = {1-e-1/30,x < 0 1-e-x/3,x≥ 0.Determine the probability density function of X.
(i)f(x)=\frac{e^{-x/3}}{3},when x>0 and f(x)=0 when x<0
(ii)f(x)=\frac{e^{-x/3}}{3};for all x ∈ R
(iii) f(x)=e^{-x/3} when x>0 and f(x)=0 when x<0
(iv) f(-/3 fll D
