Definition of Normal Distribution Probability Function:

The concept “probability of X=x” is replaced by the “probability density function fx( ) evaluated at X=x”
A picture of this function with X=x plotted on the horizontal and fx( ) evaluated at X=x” plotted on the vertical is the familiar bell-shaped (“Gaussian”) curve.
