1. Suppose we have a bag with 10 slips of paper in it. Eight slips have a 3 on them and the other two have a 6 on them. What is the expected value of the number shown when we draw a single slip of paper?
2. Suppose we have a bag with 10 slips of paper in it. Eight slips have a 3 on them and the other two have a 6 on them. What is the expected value of the number shown if we add one additional 6 to the bag.
+589 1. The expected value would be 3 since there are more slips of paper of a 3 then a 6.
+37146 Expected value (3 * 8 + 2*6)/10 = 3.6
with one additional '6'
(3*8 + 3*6 ) /11 = 3.82
