WebbLet's find the probability of independent events through an example in detail. Suppose, we have a box that contains 10 toys in which 7 toys are multi-colored and 3 are blue. Based on this we know that the probability of drawing one multi-colored toy is 7 over 10, or 0.7, and the probability of drawing a blue toy is 3 over 10, or 0.3 WebbIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event.
