Erlang B Formula

The Erlang B formula is a mathematical way to estimate the probability of call blocking in a telecommunications system, like a call center or network. It considers the number of available lines, the total traffic volume (in Erlangs, representing call duration), and predicts how likely it is that a new call will be blocked because all lines are busy. Essentially, it helps service providers plan how many lines they need to handle expected call traffic efficiently while maintaining an acceptable blocking rate.
