Probability is the chance of finding an answer given a sample distribution of the data. | |||
Likelihood is finding the best distribution of the data given a particular value of some feature or some situation in the data. | |||
You can see it as increasing the chances of a particular situation to happen, by varying the characteristics of the dataset distribution. | |||
P ( something in that range , given a a distribution (e.g. a gaussian with a certain mu and sigma) ) | |||
You take a probability distribution, and you put in a condition, and you get a new probability for that. | |||
The probability of a range of values is the area under the graph. | |||
The likelihood of finding a specific value on the other hand is a point of a curve. | |||
