Question
A) E(7Y+1) B)V(7Y+1)
Consider a discrete random variable \( Y \) with the following probability table. \[ \begin{array}{|c|c|c|c|c|c|} \hline Y & -2 & 3 & 6 & 9 & 12 \\ \hline p(y) & 0.21 & 0.07 & 0.13 & 0.34 & 0.25 \\ \hline \end{array} \] This table lists the possible values of the discrete random variable \( Y \) and their corresponding probabilities \( p(y) \). Each value of \( Y \) is associated with a probability, showing the likelihood of the variable taking that particular value. The probabilities should sum to 1, confirming they represent a valid probability distribution.
