Expected Values Values
In probability theory, we define the expected values E(x) and E(y) as the most likely outcomes of the events. They are given by the following formulas:
where S is the sample space of the random variables X and Y.
Example..
We resume the example from the last post:
Solution
Using the first quadrant of coordinate plane as as the sample space, let's call E(X) the expected time for "waiting for a table" and E(Y) the expected time for "waiting for a table". Let's calculate E(X)and E(Y):
