Answer:
a. 0.80
b. $80
Step-by-step explanation:
a. The expected value, E(Y) is the sum of: [(each of the possible outcomes) × (the probability of the outcome occurring)]. In more concrete terms, the expectation is what you would expect the outcome of an experiment to be on average:

Hence the expected value E(Y) is 0.80
b. From a above we have the expectation as E(Y)=0.80.
-The expected amount is calculated by multiplying expectation by the surcharge:

Hence, the expected amount of surcharge is $80
