Use a parametrization to express the area of the surface as a double integral. Then evaluate the integral. The lower portion cut from the sphere x squared plus y squared plus z squared equals 25x2+y2+z2=25 by the cone z equals StartFraction 3 Over StartRoot 3 EndRoot EndFraction StartRoot x squared plus y squared EndRootz= 3 3x2+y2

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.)
