Bisection Method

From the book "Numerical Methods for Engineers", by Steven C. Chapra, they state the true error is always less than the approximate error, and therefore, it is safe

Approximating the error function erf by analytical functions

My question is if I can find, or if there are known, substitutions for this non-elementary function in terms of elementary ones. In the sense above, i.e. the approximation is

Calculating approximate value for some variable much bigger than

Often in physics problems, we derive some kind of function f(x) for some physical quantity and we try to find the approximate value of the function as some variable gets too big, or close to

How to determine if a probabilities is exact or approximate

It then asked if the probabilities listed in the table is exact or approximate for various outcomes. My question is what are the indicators that determine if it''s exact or approximate?
