Thanks for editing the Math JJ 08-DEC. I reviewed the first question about the sandwich and found the answer might be wrong. For the case when Ham(huo3tui) is used, chess can be added or not added, and if added, there are 2 kind of cheeses. so the possible sanwich just for using Ham should be 3(letters)* 3(cheeses)*2(Wasabi)*2(XX)=36, the rest for Beef and pork remain the same, each 12 possible, so the total should be 36+24=60. Any discussion is welcome. Any help is aprreciated. I will be taking the test on Dec. 18th. Yvonne |
