Question 438087
 a box contains 25 balls and 5 of them are worth $25.00 and the remainder are valued at $10.00, I reach in the box, remove one and give it to Billy. Then I reach in again and repeat the process a second time. What is the probability that the second ball was worth $25.00 if the first one was worth $10.00?
---
There are 24 balls left in the box.
5 of them are $25 balls.
P(2nd ball = 25) = 5/24
