What is random process example?

Tossing the die is an example of a random process; • The number on top is the value of the random variable. 2. Toss two dice and take the sum of the numbers that land up. Tossing the dice is the random process; • The sum is the value of the random variable.

What do you mean by mean and variance of a random process?

Mean of random variables with different probability distributions can have same values. Hence, mean fails to explain the variability of values in probability distribution. Therefore, variance of random variable is defined to measure the spread and scatter in data.

How do you find the mean of a random process?

Mean Function of a Random Process:

In particular, if Xn,n∈J is a discrete-time random process, then μX(n)=E[Xn], for all n∈J. Some books show the mean function by mX(t) or MX(t). Here, we chose μX(t) to avoid confusion with moment generating functions.
