You can put this solution on YOUR website! A bag contains 9 red balls numbered 1,2,3,4,5,6,7,8,9 and 6 white balls numbered 10,11,12,13,14,15. One ball is drawn from the bag. What is the probability that the ball is white, given that the ball is odd-numbered?
---------------------
P(white|odd) = P(white AND odd)/P(odd)
= (3/15)/(8/15)
---
= 3/8
