An urn contains 5 balls, two of which are marked $1, two $4, andone $10. A player is to draw two balls randomly and withoutreplacement from the urn. Let X be the sum of the amounts marked onthe two balls. Find the expected value of X.
Side note:
I know Rx={2,5,8,11,14}
and P(X=2) = 1/10 ... etc
I just need a proper explanation for finding the values ofP(X=2), P(X=5), etc. Thanks!
