Repeat the experiment many times and take the mean. Here is a probability distribution for a random variable X:
|
Value of X
|
-1
|
2
|
|
Probability
|
0.3
|
0.7
|
A single experiment generates a random value from this distribution. If the experiment is repeated many times, what will be the approximate value of the mean of these random variables? Give a reason for your answer.
