5. there were some blue marbles and white marbles in a bag.
if 70 blue marbles were to be removed from the bag, the ratio of the number of blue marbles to the number of white marbles would be 3: 4. if 112 white marbles were to be removed from the bag instead, the ratio of the number of blue marbles to the number of white marbles would be 8: 7. when 48 more blue marbles were to be added into the bag, what percentage of all marbles would be blue marbles?

Afriend of mine is giving a dinner party. his current wine supply includes 10 bottles of zinfandel, 8 of merlot, and 11 of cabernet (he only drinks red wine), all from different wineries. (a) if he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? ways (b) if 6 bottles of wine are to be randomly selected from the 29 for serving, how many ways are there to do this? ways (c) if 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? ways (d) if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (round your answer to three decimal places.) (e) if 6 bottles are randomly selected, what is the probability that all of them are the same variety? (round your answer to three decimal places.)
