Probability Basic Conspectus
| P(E) as the ratio m/n |  If P(E) = 1, then it is called a ‘Certain Event’. If P(E) = 0, then it is called an ‘Impossible Event’. The probability of an event E is a number P(E) such that: 0 ≤ P(E) ≤ 1 For any event E, P(E) + P(E¯) = 1, where E¯ stands for ‘not E’. E and E¯ are called complementary events. |
