We use probability to determine if something is likely to happen or not. If the probability is that the incident will definitely happen, then that probability figure is 100% or 1, while if the incident definitely cannot happen the probability figure is 0% or 0; every other possible probability lies somewhere between 0 and 1 (or 0% and 100%).

∙ 10y agoBecause very many events are not deterministic: there is a degree of randomness in them and probability enables one to made informed guesses as to their outcomes. Radioactive decay is a classic example of such a process. Some processes, such as the weather system, are so complex and involve a huge number of variables with many feedback loops. It is impossible to take account of all the relevant factors and so, even though the process may be deterministic, it is too complicated to model accurately. Probability allows one to make simplifying assumptions and then make probabilistic predictions about the weather rather than give up because there is no accurate model.

Does the weather report use the empirical probabilities or theoretical probabilities in its weather forecast?
Empirical probabilities.
How do you combine probabilities?
like for or we use + and for 'and' we use multiplication
How do you find the probability of an event followed by another event?
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
What can you use to find experimental probabilities?
Repeated trials.
Strategies you can use to find theoretical probabilities?
a tree diafram
What function do you use to calculate the probabilities of compound events?
To calculate the probabilities of compound events, you can use the multiplication rule or the addition rule, depending on whether the events are independent or mutually exclusive. The multiplication rule is used when the events are independent, and you multiply the probabilities of the individual events. The addition rule is used when the events are mutually exclusive, and you add the probabilities of the individual events.
Who do you Add Probabilities?
I do not add probabilities to anybody!
What is the sum of all probabilities?
Sum of all probabilities is 1.
What does math have to do with a peditrician?
A peditrician might need to use math to determine the kind of disease for probabilities.
When was Statistical Probabilities created?
Statistical Probabilities was created on 1997-11-22.
What is the sum of the probabilities of all possible outcomes?
The sum of the probabilities of all possible outcomes is 1.
Bayes theorem uses Prior probabilities with additional information to compute posterior probabilities?
False
