The null hypothesis may presume that there is no chain of circumstances between the items being tested which may cause an outcome for the test. WebbProbability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
