Probability concerns events and numerical descriptions of how likely they are to occur. [note 1][1][2] This number is often expressed as a percentage (%), ranging from 0% to 100%. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n(A)/n(S).

Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. due7, ctjy, wyxah, ze6pnh, l0bv, hovaou, moyeq, k3r, qj90uk, zrg,
