The chapter Probability is part of a larger unit, Unit Six- Probability, which is worth 8 out of a total of 80 points. This chapter includes two exercises as well as a miscellaneous activity to assist students fully grasp the basics of probability.Following are the concepts discussed in Chapter 13 of NCERT Solutions for Class 12 Maths:

1. 0 ≤ P (E|F) ≤ 1, P (E′|F) = 1 – P (E|F)P ((E ∪ F)|G) = P (E|G) + P (F|G) – P ((E ∩ F)|G)
2. P (E ∩ F) = P (E) P (F|E), P (E) ≠ 0P (E ∩ F) = P (F) P (E|F), P (F) ≠ 0
3. If E and F are independent, then P (E ∩ F) = P (E) P (F)P (E|F) = P (E), P (F) ≠ 0P (F|E) = P (F), P(E) ≠ 0
4. Total probability theorem
5. Bayes’ theorem
6. A random variable is a real-valued function whose domain is a random experiment’s sample space.
7. Var (X) = E (X2) – [E(X)]2
8. If the below conditions are satisfied, then the Trials of a random experiment are called Bernoulli trials :
9. A set number of trials should be available.
10. The trials should be self-contained.
11. There are only two possible outcomes in each trial: success or failure.
12. In each trial, the chances of success are the same.
