Question

What is probability?

Answer 1

Definition of the probability:

Probability is a branch of mathematics that deals with the occurrence of a random event where probability means the possibility of occurring of any event. The value of the probability is expressed from zero to one.

The probability $P\left(E\right)$of an event $E$ is computed as:

$\mathbf{P}\mathbf{\left(}\mathbf{E}\mathbf{\right)}\mathbf{=}\frac{\mathbf{Number}\mathbf{}\mathbf{of}\mathbf{}\mathbf{favourable}\mathbf{}\mathbf{outcome}}{\mathbf{Total}\mathbf{}\mathbf{number}\mathbf{}\mathbf{of}\mathbf{}\mathbf{outcomes}}$

Hence, the probability is the possibility of the occurrence of a random event.
