Quizplus · Accepted Answer

The variance of a random variable is denoted as var(Y) and is equal to the expected value of the squared deviation of Y from its mean, i.e., var(Y) = E[(Y - E[Y])^2]. Without knowing the specific distribution of Y, we cannot calculate the value of var(Y). Therefore, none of the options given can be determined as the correct answer.
