I'm not entirely confident with my answers.
B) because you want to choose at least one of the 3 even numbered white balls
I was wondering if I could get some help with a problem. I have thought about this for a long time and can't figure it out. I don't need to solve the problems (at least not yet), I just need to know if they have different answers and if so, why. I thought they should all have the same answer, but my calculations are not working out that way :-(
Imagine a glass with 6 white balls numbered 1-6 and 4 black balls numbered 1-4. 3 balls are chosen at random.
A) What is the probability you choose 3 white balls given you choose at least 1 white ball.
B) What is the probability you choose 3 white balls given you choose at least 1 even numbered white ball?
C) What is the probability you choose 3 white balls given you choose white ball #2?
