Probabibility Independent events

[QUOTE="PeroK, post: 6064600, member: 493650"] It's clear that the first card and the second card are not independent. The probability that the second card is a spade depends on whether the first card is a spade etc. But, does the probability that the second card is a queen depend on the suit of the first card? You can try to resolve the issue as follows: Before we start we know that the probability that the second card is a queen is 1/13. Then, we draw the first card and I look at it and tell you it's a spade. Now, is the second card more likely or less likely to be a queen? Or, is it still 1/13? What if the first card was a diamond? Or a heart? Or a club? Perhaps it's clear, therefore, that the [U]denomination[/U] of the second card does not depend on the [U]suit[/U] of the first card? Finally, however, I would recommend checking this out using conditional probabilities. It's a good exercise in any case. [/QUOTE]
