Stochastic Independence
Independence: Two outcomes A and B are independent if:
P(A \cap B) = P(A) \cdot P(B)
This can also be written as (conditional probabilities):
P(B|A) = P(B)
This basically means that A happening has no influence on B happening (think more in terms of multiple outcomes happening in a row).
