Aiden calculated the area of triangle QRS below by finding half the product of 1.5 and 1.1.

Triangle Q R S has a base of 5.4 and a height of 1.1. Another side has a length of 1.5.

What error did Aiden make?
Aiden should have found half the product of 1.1 and 1.2 because the 1.5 line is not a dotted line in the figure.
Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to the 1.1 line.
Aiden should have found half the product of 1.5 and 1.2 because the 1.1 line is not perpendicular to the 1.5 line.
Aiden should have found half the product of 1.5 and 5.4 because the 1.1 line is a dotted line and not part of the figure.

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.)
