#revolutioneducation #class10mathematics #probability Probability is a number between 0 and 1 that describes the chance that a stated event will occur. An event is a specified set of outcomes of a random variable. Mutually exclusive events can occur only one at a time. Exhaustive events cover or contain all possible outcomes. A random variable is a quantity whose outcome is uncertain. Probability is a number between 0 and 1 that describes the chance that a stated event will occur. An event is a specified set of outcomes of a random variable. Mutually exclusive events can occur only one at a time. Exhaustive events cover or contain all possible outcomes. The two defining properties of a probability are, first, that 0 ≤ P(E) ≤ 1 (where P(E) denotes the probability of an event E), and second, that the sum of the probabilities of any set of mutually exclusive and exhaustive events equals 1.
