Philosophy of probability

Philosophy of probability is the study of the nature of probability. It asks questions like: what is probability? Is it a real thing? How do we measure it? Probability is a measure of how likely something is to happen. It can be used to decide what choices to make and how to plan for the future. Probability is usually represented as a number between 0 and 1. 0 means that something is impossible and 1 means it is certain. Anything in between 0 and 1 shows how likely something is. For example, if the probability of it raining tomorrow is 0.5, that means it is equally likely for it to either rain or not rain tomorrow.
