Probability of two draws without replacement

The first marble is not put back, so the second draw has fewer marbles. Multiply the two probabilities.

1. A bag has 6 red and 7 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
2. A bag has 3 red and 1 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
3. A bag has 7 red and 3 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
4. A bag has 3 red and 7 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
5. A bag has 7 red and 10 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
6. A bag has 3 red and 2 blue marbles. Two marbles are drawn one after the other and the first is NOT put back. What is the probability that both are red? Write a fraction in lowest terms.
