The chapter Probability itself makes up to a whole unit, Unit Six- Probability, that carries 8 marks of the total 80 marks. There are 2 exercises along with a miscellaneous exercise in this chapter to help students understand the concepts related to Probability thoroughly. Some of the topics discussed in Chapter 13 of NCERT Solutions for Class 12 Maths are as follows:

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)
P (E ∩ F) = P (E) P (F|E), P (E) ≠ 0
P (E ∩ F) = P (F) P (E|F), P (F) ≠ 0
If E and F are independent, then
P (E ∩ F) = P (E) P (F)
P (E|F) = P (E), P (F) ≠ 0
P (F|E) = P (F), P(E) ≠ 0

The theorem of total probability
Bayes’ theorem
A random variable is a real-valued function whose domain is the sample space of a random experiment.
Var (X) = E (X2) – [E(X)]2
Trials of a random experiment are called Bernoulli trials if they satisfy the
following conditions :
There should be a finite number of trials.
The trials should be independent.
Each trial has exactly two outcomes: success or failure.
The probability of success remains the same in each trial.
