# A detailed guide on how to find probability

If you are interested in learning about **how to find probability **or** how to calculate probability**, then you should know that **finding probability** and learning **how to solve probability **is truly very easy. What you basically need to do to **calculate probability **is just divide the number of times that the event is expected to occur by the total number of probable outcomes.

## What is the basic probability formula that I need to use?

Just so you know, probability is a measure that indicates how likely the occurrence of an event is with the help of a basic **statistics probability formula**, and these events are basically known as the outcomes of an experiment. For this purpose, the **probability formula **that you need to use is the ratio that exists between the number of favourable outcomes and the sum of all possible outcomes of an experiment. Hence, the **calculating probability formula** comes down to being:

*Number* *of* *Favorable* *Outcomes/Total* *Number* *of* *Possible* *Outcomes*

The **formula for probability **is best used in situations wherein every single outcome holds equally likely chances of taking place. If truth be told, probability and learning **how to do probability **is all about prediction. In case the probability that an event is going to take place is ‘x’, then the probability that it would not take place will become ‘1-x’. Also, in cases where the probability that an event is going to take place is ‘a’, whereas the independent probability that some other event is going to take place is ‘b’, then the possibility that both of the events are going to take place will become ‘ab’. Hope you understand **how do you find probability **now!

## Apart from that, what is the conditional probability formula?

Now that you have learnt **how to find the probability**, let’s move on to learning about the **formula for probability **that is conditional. Defining conditional probability is extremely easy – just as learning how to **find the probability**. If truth be told, out of all the **probability formulas **out there, the one that is easiest is that of **calculating probability** known as conditional probability.** **See, in places where the probability of an event denoted by A is provided, and you need to **find probability **of another distinct event called B based over the event A, then the probability that you would obtain is known as the conditional probability of event B given A. Its basic representation or the general **conditional probability formula **that is used for **finding the probability **is P(B/A).
