The anticipation body function, $f_\left(x\right),$, represents the administration of the accidental capricious $X,$. Wikipedia defines the PDF as a smoothed out adaptation of the accidental variables histogram of its distribution. Basically, the beyond the amount of $f_\left(x\right),$ for a specific amount $x,$ agency the added generally that amount $x,$ will arise if allotment a accidental capricious of its blazon of distribution.

The absolute breadth beneath the ambit formed by $f_\left(x\right),$ will consistently be one, back that absolute breadth represents the anticipation that the accidental capricious $X,$ will be a value.

PDF for an Exponential RV

One way to account the PDF is to differentiate its CDF, $fracF_\left(x\right) = f_\left(x\right),$
