RD Sharma Class 12 Maths Solutions Chapter 32 - Mean and Variance of a Random Variable

The mean of a discreet random variable X is the weighted average of the possible values that the random variable may take. Unlike the sample mean of a set of observations, which gives equal weight to each observation, the mean of a random variable is xi by its likelihood, pi.
