Bayes' theorem

Bayes' theorem helps us figure out the probability of something happening in the future, based on what we know about it now. It helps us figure out how likely it is that a certain thing might happen. Think of it like a math equation, that lets us predict how likely it is that something will happen, given certain information. For example, let's say we want to figure out the probability that it will rain tomorrow. We could use Bayes' theorem to calculate the probability based on the current temperature and other information about the weather.
