I have 61 cards in my deck. 22 are red, 39 are blue. Whats the percentage of picking up a red card?
Another question to add to that. Lets say this was a game of cards, I have a starting hand of 7 cards, what's the percentage of getting red cards in my starting hand?
Knowing the percentage of having X red cards in my hand, whats the percentage of getting a red card each time I draw afterwards?
