A friend of mine is giving a dinner party. His current wine supply includes 9 bottles of zinfandel, 7 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?(b) If 6 bottles of wine are to be randomly selected from the 30 for serving, how many ways are there to do this?

a) 783 ways; b) 593775 ways

Step-by-step explanation:

a) Your friend wants to select 3 zinfandel out of 9 from the supply in a particular order, which means:

= 783

In the dinner party, the friend will have 783 ways of serving the zinfandel.

b) Now, your friend want to select 6 bottles out of 30 in no particular order and randomly selected. So:

= 593775

If you select 6 bottles randomly from 30, you will have 593775 ways of doing it.

change of stock price/initial stock price on friday * total stock value = change of stock value
