NCERT Solutions Class 12 Maths Chapter 13 Exercise 13.4 Probability

NCERT Solutions for Class 12 Maths Chapter 13 Exercise 13.4 Probability explains the probability distribution of a random variable, its mean, and variance. A random variable is a real-valued function whose domain is the sample space of a random experiment. The probability distribution of a random variable defines the probability of its value that is unknown. The mean or expectation of a random variable X is the sum of the products of all possible values of X by their respective probabilities. It is represented by µ or E (X) = x₁ p₁+ x₂ p₂ + ... + x_n p_n. Variance is used to calculate the variability or spread in the values of a random variable. The variance of X is denoted by Var (X) and is calculated using the formula Var(X) = E(X – µ)², where µ denotes the mean of X.

The sums provided in this exercise are majorly focused on imparting a clear understanding of applying all these concepts especially to find the mean and variance of a random variable. NCERT solutions Class 12 Maths Chapter 13 Exercise 13.4 succinctly covers the whole topic of random variables to promote precise error-free learning. There are 17 sums provided in this exercise for students to learn a step-by-step understanding of the probability distribution of a random variable, its mean, and variance.
