Question 1

Step 1:

Probability theorem.

The probability that an event occurs + Probability that an event did not occur = 1

Step 2:


\begin{gathered} \text{Probability that event E occur P(E) = }(2)/(3) \\ \text{Probability that event E did not occur q(E) = ?} \end{gathered}

Step 3


\begin{gathered} p(E)\text{ + q(E) = 1} \\ (2)/(3)\text{ + q(E) = 1} \\ q(E)\text{ = 1 - }(2)/(3) \\ q(E)\text{ = }(1)/(3) \end{gathered}

Final answer

The probability that E will not occur = 1/3
