Answer:

(C). ​(Probability of state A*Value in state A)+(Probability of state B*Value in state B)

Explanation:

The expected value of a probability distribution, E(X) is defined as:


E(x)=\sum_(i=1) ^(k) x_(i) \cdot P(x_(i))\\$Where x=An Outcome\\P(x)=Probability of that Outcome

Given Outcome A and B, the Expected Value therefore is:

Expected Value = ​(Probability of state A*Value in state A)+(Probability of state B*Value in state B)
