Does anyone remember math? Not the practical kind you use in real life, like figuring 15% for a tip at Longhorn Steakhouse, but the useless high-school kind? I've been doing a few practice GRE math questions today and I'm a little shocked at how very little of that stuff I do actually remember. Did you know that all of the exterior angles of a figure always add up to 360 degrees? I sure didn't. I'm not sure I ever knew that. I don't even remember how to multiply fractions anymore. So doing these practice GRE math questions has been an exercise in humility. I know so very very little. When I go in tomorrow for a "practice" test at a Kaplan testing center, I'm fully expecting to embarrass myself on the quantitative section. Here's an example of a question that I took a good look at, and then straight up gave up on. (I'm choosing the hardest one I've seen so far just to keep everyone on their toes):
17.) Jane must select three different items for each dinner she will serve. The items are to be chosen from among 5 different vegetarian and 4 different meat selections. If at least one of the selections must be vegetarian, how many different dinners could Jane create?
The explanation in the back of the book made my mind hurt. I encourage you to give it a shot. 1 in 5 of you will get it right. Or will you? Or are those odds? I don't know odds, and 1 in 5 of you probably won't get it. 1 in 10? Less than that? Peggy?
Anyway, if anyone is interested, I'll post up the answer and the explanation tomorrow.
