In probability, how do you represent the likelihood of an event occurring?

The likelihood of an event occurring in probability can indeed be represented in multiple formats. This versatility allows for better communication and understanding depending on the context.

A fraction representation is common, particularly when discussing probabilities in terms of favorable outcomes over possible outcomes. For example, if there are 3 favorable outcomes out of 10 total possibilities, the probability can be expressed as 3/10.

When expressed as a decimal, probability becomes more straightforward, especially when calculations require addition or multiplication of probabilities. The same example of 3 out of 10 can be converted to a decimal as 0.3.

Lastly, probabilities can also be represented as percentages, making them easy to interpret in everyday contexts. To convert the decimal representation into a percentage, simply multiply by 100. So, 0.3 can be expressed as 30%.

All these formats convey the same information about the likelihood of an event occurring, allowing flexibility in their use across various applications in statistics and probability.
