Danny keeps five cards with the picture of a cat and six cards with the picture of a dog on a table face down, so the pictures are hidden. He mixes up the cards then turns one card over and finds the picture of a dog on it. He removes this card from the table and turns over another card.
What is the probability that the card Danny turns over has a dog on it?
fraction 4 over 10
fraction 5 over 11
fraction 5 over 10
fraction 5 over 6
