In A level mathematics we use a the symbol to represent the conditional probability in which we say given. Negative probabilities can be interpreted as follows. The law of total of total probability gives you a method for computing the unconditional or total probability of an event B if you know its conditional probabilities with respect to some other event A and the probability of A.

183 1 1 gold badge 1 1 silver badge 12 12 bronze badges endgroup 3. A probability of 15 could be interpreted as youre 150 sure the event will happen - kind of like giving a 150 effort. Expression of the Conditional Probability.

Since there are 13 spades in 52 cards therefore the unconditional probability of B is 13 52. Compute conditional probabilities directly and using Bayes theorem and check for independence of events. And in our case.

And we write it as Probability of event A and event B equals the probability of event A times the probability of event B given event A Lets do the next example using only notation. The outcome of a random event cannot be determined before it occurs but it may be any one of several possible outcomes. Divide the number of events by the number of possible outcomes.
