WebbIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event. For example, the probability that a fair coin shows "heads" after being flipped is 1 / 2 1/2 1 / 2 1, slash, 2 . Webbfrom a box (with replacement), etc. If the probability of a particular event occurring (for example, getting a Heads, rolling a 5, or picking a blue ball) is p, then the event will occur in a fraction p of the trials, on average. Some examples are: ‹ The probability of getting a Heads on a coin ﬂip is 1/2 (or equivalently 50%).
