Probability problem.
I shuffle a deck of 10 cards
Only one card says that you Win
You get to pick 2 random cards.
Now we agree your odds of winning would be 2/10
But what if you turn the first card and it's a blank.
What are the odds that your second card are a win? Is it still 2/10, or did it drop to 1/10 or perhaps it's now 1/9?
