# Probability Formulas Probability Formulas:- The likelihood recipe is utilized to register the likelihood of an occasion to happen. To review, the probability of an occasion happening is called likelihood. When an arbitrary trial is engaged, one of the primary inquiries that come to us is: What is the likelihood that a specific occasion happens? A likelihood is a shot at expectation. At the point when we accept that, suppose, x be the odds of happening an occasion then simultaneously (1-x) are the opportunities for “not occurring” of an occasion. ## Recipe to Calculate Probability (Formula to Calculate Probability)

OR

P(A) = n(A)/n(S)

###### Where,
1. P(A) is the likelihood of an occasion “A”
2. n(A) is the quantity of ideal results
3. n(S) is the complete number of occasions in the example space

## Fundamental Probability Formulas

###### Let An and B are two occasions. The likelihood equations are recorded underneath:
S.R. NO. All Probability Formulas List in Maths
1 Probability Range 0 ≤ P(A) ≤ 1
2 Rule of Addition P(A∪B) = P(A) + P(B) – P(A∩B)
3 Rule of Complementary Events P(A’) + P(A) = 1
4 Disjoint Events P(A∩B) = 0
5 Independent Events P(A∩B) = P(A) ⋅ P(B)
6 Conditional Probability P(A | B) = P(A∩B) / P(B)
7 Bayes Formula P(A | B) = P(B | A) ⋅ P(A) / P(B)
