Let $\displaystyle {X}$ represent the full height of a certain species of tree. Assume that $\displaystyle {X}$ has a normal probability distribution with a mean of 63.3 ft and a standard deviation of 5.2 ft.

A tree of this type grows in my backyard, and it stands 52.4 feet tall. Find the probability that the height of a randomly selected tree is as tall as mine or shorter.

$\displaystyle {P}{\left({X}<{52.4}\right)}$ =

My neighbor also has a tree of this type growing in her backyard, but hers stands 62.8 feet tall. Find the probability that the full height of a randomly selected tree is at least as tall as hers.

$\displaystyle {P}{\left({X}>{62.8}\right)}$ =
