Lesson 15.3
The theoretical(classical)probability of an event E,written as P(E), is defined as [P (E) = Number of outcomes favourable to E / Number of all possible outcomes of the experiment] where we assume that the outcomes of the experiment are equally likely.
Probability of an event: The probability of a sure event (or certain event) is 1
Probability of an event: The probability of an impossible event is 0
