If I have a bag with 8 balls, 4 of them red and 4 of them white, which is the probability than when I take a sample size 2 without replacement, both balls are red.
I did 1/2 X 3/7, but this only occurs if the first ball was red.
If not, it is 1/2 X 4/7 and it is a different thing...so, what should I do?
