WebbIn summary, probability is a measure of the likelihood of an event, and it relates to symmetrical outcomes and relative frequencies by assigning a number between 0 and 1 to each possible outcome based on the observed frequencies. Probability can also be subjective in that it can depend on individual knowledge, beliefs, and biases. WebbPractice Venn diagram probability questions. 1.
