through 3, consider a bag that contains 3 red marbles, 7 green marbles,
5 blue marbles, and 1 yellow marble. Two marbles are pulled at random from the bag.
1. What is the probability that both marbles are blue, if the first marble is replaced
before the second marble is drawn?
2. What is the probability that both marbles are blue, if the first marble is not
replaced before the second marble is drawn?
3. What is the probability that one marble is green, and one marble is yellow, if the
marble is not replaced after the first draw?
For questions 4 through 6, consider rolling a die, then drawing a card from a standard
deck of playing cards.
4. What is the probability of rolling a 4, then drawing a queen?
5. What is the probability of not rolling a 3, then drawing a red card?
6. What is the probability of rolling a prime number, then drawing a face card?
7. What is the probability of rolling a number greater than 2, then drawing a spade?
