Finding Expected Value, Variance, and Standard Deviation In Exercises 23–26, find the expected value, variance, and standard deviation for the given probability distribution. See Examples 4, 5, and 6.
x  1  2  3  4  5 
P(x) 





To calculate: The value of expected value, variance and standard deviation for given probability distribution.
x  1  2  3  4  5 
Given Information:
The random variable and their probability are given as
x  1  2  3  4  5 
Formula used:
If the set of values of a discrete random variable consist in district values
If mean
And the standard deviation is,
Calculation:
Consider the given information
And,
And,
Consider the primary equation and substitute the given values
