Compute the mean and variance of the random variable X.
Answer to Problem 175SE
The mean of the random variable X is
The variance of the random variable is 0.0104.
Explanation of Solution
Given info:
The random variable X be equally likely to takes the values
Calculation:
Equally likely outcomes:
Outcomes of an experiment is said to be equally likely if they have equal chance of occurrence.
The Mean of a discrete Random Variable:
The mean of the discrete random variable X is denotes as
The Variance of a discrete Random Variable:
The variance of the discrete random variable X is denotes as
Here, X takes the values
Therefore,
Thus, the mean of the random variable is
Thus, the variance of the random variable is 0.0104.
