Hi, I had a problem in class that goes like this
There's a bag with 3 red balls and 2 blue balls. You choose randomly 2 balls out of the bag. What's the probability distribution function for the number of red balls?
Given X =x corresponds to the number of red balls chosen when you choose 2 balls out of the bag.
What are the probabilities of X= 0, X =1, X=2? In other words, what are the probabilities of choosing 0 , 1 , 2 red balls when you choose 2 balls out of the bag?
Is there anyway to solve this as a Conditional Probability?
Can I interpret it as the probability of choosing x red balls (0 to 2) given that you're choosing 2 balls?
Thanks a lot!
