PROBABILITY OF TWO INDEPENDENT EVENTS
PROBABILITY OF TWO DEPENDENT EVENTS
you find the probability of A and you don't replace it to find Bthen you multiply the dependent events to find the probability of the event

Sup Jonsie,
The first one I understand but I'm not sure I get the other. Maybe if you had some examples.
I did understand the first one but not the second one. You should use example and i would put number 2 like this: after you find A take B times A to get your answer. Example You have a total of 20 tiles the letters are 4 As, 3 Us, 5 Es, 7 Is, and 1 O what is the probability that you draw a E after A with out replacing. A=4/20 or 1/5 times B=5/19 the answer is 1/19. If you do replace the tile is 1/5 times 1/4 the answer 1/20.
