Yes.

anonymous · Answer

Wasn't a yes or no question, I'm asking you.

If I pick a marble, then pick another one does the first marble I picked affect the probabilities for the second?

anonymous · Answer

Or the cards. If I pick a card, put it back, and pick another, does the second outcome depend on which card I picked the first time?

Think about it this way.

If I have a bag of 3 marbles, 2 red, one black. And I pick a marble and it's black, what's the odds that if I pick another marble I will get a red one?
