How are weather probabilities determined
Web8 de fev. de 2013 · There are different ways to determine probability. Experimental probability, which is determined by observing outcomes of experiments. Such as a coin toss- probability of getting a heads is 1/2. Numbers are unique to each experiment. Theoretical probability can be found without having to do an experiment and will not vary. WebP (A or B) = P (A)+P (B)-P (A and B). If A and B are independent (that is, the occurrence of a specific one of these two events does not influence the probability of the other event), then. P (A and B) = P (A)P (B). Without the assumption of independence, we have to modify this rule by replacing one of the individual probabilities by a ...
