Tessa keeps seven cards with the picture of a king and three cards with the picture of a queen on a table face down, so the pictures are hidden. She mixes up the cards then turns over one card and finds the picture of a king on it. She removes this card from the table and turns over another card.
What is the probability that the card Tessa turns over has a picture of a king on it?
fraction 1 / 7
fraction 2 / 9
fraction 6/ 10
fraction 6 / 9

Best ResponseYou've already chosen the best response.0plasmataco had the right idea after throwing the king away on the first draw 7 1 = 6 kings left 101 = 9 cards total probability of king on second draw = (# of kings left)/(# of cards total left) probability of king on second draw = 6/9 = 2/3
