Question

There are two Gaussian curves below (Plots A and B), along with the respective R source codes.
Looking at the plots and the source codes provided, identify the parameters of respective 
Gaussian pdf's (probability density functions) and the numeric value of x in the PDF F(x)
express the areas under the curves in terms of F(x). ( Do not calculate those areas.Your answers must be like F(x) or 1- F(x)  for a relevant value of x.) 

Below is the source code and image for part B

X -4 -2 0 N 4 O 8 0.00 0.05 0.10 0.15 0.20
