Independent

Definition:

• If the outcome of a probabilistic event does not affect the probability of another event, the the events are independent.

Example:

• assume that a normal six-sided die is being rolled twice to determine the probability of rolling a 1 twice. The result of the first roll does not affect the probability of rolling a 1 on the second roll. Since the probability if rolling a 1 on the first roll is 1/6 and the probability of rolling a 1 on the second roll is also 1/6, then the probability of rolling two 1s in a row is (1/6) x (1/6) = (1/36)
