Answer:
Use the following formula to compute the mean of a discrete random variable. E(X) = μx = Σ [ xi * P(xi) ]
Explanation:
The mean of the discrete random variable X is also called the expected value of X. Notationally, the expected value of X is denoted by E(X). Mean of a discrete random variable
This can be thought of as the weighted average of the six possible values 1,2,…,6, with weights given by the relative frequencies. ...
The mean μX of a discrete random variable X with probability function pX(x) is given by. where the sum is taken over all values x for which pX(x)>0.
