# What is the probability? Find out now!

Have you recently started out with your Statistics class and are wondering as to what is the probability? See, there are a number of events that cannot be predicted with utmost certainty. For this purpose, these events and their outcomes are expressed as being ‘likely’ to occur with the help of probability. For instance, the best examples of probability include: whenever we toss a coin, there aren’t any sureties with regards to its outcome. The possible outcomes are two: either it would result in heads (H) or tails (T). In such a condition, probability statistics claims that the probability of the coin landing on heads or H is ½, whereas the probability of the coin landing over tails is also ½. This can be shown over a probability table and probability Venn diagram as well. Here is a probability tree diagram for the same:

Generally speaking, the basic probability notation or formula is:

 Probability of an event happening = Number of ways it can happen Total number of outcomes

## Probability rules that you should know about

There are certain probability rules with basic probability terms that you should know about for the effective outcome of your problems. Here’s a look into them:
