What do you understand by Mathematical expectation?
उत्तर
The expected value of a random variable gives a measure of the center of the distribution of the variable.
In other words,
E(X) is the long-term average value of the variable.
The expected value is calculated as a weighted average of the values of a random variable in a particular experiment.
The weights are the probabilities.
The mean of the random variable X is µX = E(X).
