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) to
express the areas under the curves in terms of F(x). ( Do not calculate those areas. The answers must be like F(x) or 1-F(x) for a relevant value of x.)
