Probability Formula:

Probability Formula

Or

$$\text{P(A)}\;=\;\frac{\text{n(E)}}{\text{n(S)}}$$

Where,

P(A) shows probability of an event.
n(E) shows number of favorable outcomes.
n(S) is the total number of events in the sample space.

Some Basic Probability Formulas

Suppose that the A and B are two events.

Probability Range 0 ≤ P(A) ≤ 1
Addition P(A∪B) = P(A) + P(B) – P(A∩B)
Complementary Events P(A’) + P(A) = 1
Disjoint Events P(A∩B) = 0
Independent Events P(A∩B) = P(A) ⋅ P(B)
Conditional Probability P(A | B) = P(A∩B) / P(B)
Bayes Formula P(A | B) = P(B | A) ⋅ P(A) / P(B)
