The Venn diagram for such an event is shown below: The above Venn diagram clearly shows that X and Y are independent. She thinks to herself: What is the probability of James selecting an ace and then, without replacing the card, selecting another ace? Conditional Probability and Independence Biostatistics College of Direct link to Jerry Nilsson's post In this case we have thre, Posted 2 months ago.
