A deck of cards has 3 blue 4 black and 6 purple You pick 2 cards from the deck cards are not returned to the deck after they are picked whats the probability that two blue are picked?

Answer 1

First you have 3 blues out of 13 cards, so the first card has probability 3/13. Then you have 2 blues out of 12 cards, so the second card has probability 2/12 or 1/6. The probability of both being blue is the product of these probabilities:

P(two blues) = P(first blue) * P(second blue) = (3/13) * (1/6) = 3/78 or 1/26
