inorganic chemistry - What is the difference between the mean radial distance and the most probable radial distance of an orbital?


I was reading JD Lee's Concise Inorganic Chemistry and it has given some values of mean radial distance which is increasing from s to p to d orbital. I had earlier read that the most probable radial distance of an orbital has the order s>p>d>f. This makes me wonder what is the difference between the mean radial distance and most probable radial distance. Also, why is the order of mean distance reverse from that of most probable radial distance? Also can you please explain why is the energy of an orbital proportional to mean radial distance as given in the book? Source: Concise Inorganic Chemistry by JD Lee; sorry for the bad photography
