Solution 1

The expected value (E(X)) of a random variable is calculated as the sum of all possible outcomes each multiplied by their respective probabilities.

In this case, X can take on the values 3 and 8.

Given that P(X = 3) = 0, this means that the random variable X will never take on the value 3.
