B: You get salmonella poisoning. The possibility of happening or not happening of an event is known as probability. diamonds, given that the first four were diamonds 25. This principle can be extended to any number of individual. Independent and Dependent Events The events A and B are said to be independent if the occurrence or non-occurrence of event A does not affect the probability of occurrence of B. If the probabilities are substantially different, then we say the variables are dependent. Probability Models A probability model is a mathematical representation of a random phenomenon. Examples of Outcome. A Markov chain probability will look at the sequences of events where each probability is dependent on the results of a prior event or events. Dependent Events Events are dependent when the outcome of one event affect the outcome of a second event.
