Probability is a branch of mathematics that deals with the likelihood of an event occurring. It is used to quantify the uncertainty or chance of a particular outcome happening. The probability of an event happening is usually represented as a number between 0 and 1, with 0 meaning the event is impossible and 1 meaning the event is certain to happen.

To calculate the probability of an event, you need to know the number of favorable outcomes and the total number of possible outcomes. The probability can be calculated using the following formula:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

For example, let’s say you have a bag of colored marbles. There are 5 red marbles, 3 blue marbles, and 2 green marbles. If you randomly choose a marble from the bag, the probability of selecting a red marble would be:

Probability of selecting a red marble = (Number of red marbles) / (Total number of marbles) = 5 / (5 + 3 + 2) = 5/10 = 0.5

So, the probability of selecting a red marble is 0.5 or 50%.

It’s important to note that the probability can also be expressed as a fraction or a percentage. In the example above, the probability of selecting a red marble could also be written as 1/2 or 50%.

Probability can be used in various real-life situations, such as determining the likelihood of winning a game, predicting the outcome of an event, or analyzing data in statistics. It is a fundamental concept in mathematics and has applications in many fields.
