Each of 5 men played a game of chess with each of 5 women, and then each woman played a game of chess with each of the other women. How many games of chess were played?
(I did remember how to do the first part - apparently I never learned a procedure for doing the second part...or, more likely, I failed to generalize the procedure I did learn, whatever that was...)
This is what happens when you're constantly teaching yourself whole content areas in one afternoon so you can reteach them to your kid FOR THE TEST, etc.
The next time you see the material you have no clue.
Combinations and permutations can be incredibly hard; not the formulas, but when and how to apply them. There is a tendency to misread or misunderstand the problem statement. For this problem, one should be able to draw a picture or diagram and figure it out, but that's not math.
Yes, I'm sure he will.
ReplyDeleteOh dear. I just tried it, I suspect I have no option but to subscribe too.
ReplyDeleteNothing like a daily test to remind myself that my brain is shrinking, or possibly just leaking?
Cheers
I've been ignoring my questions.
ReplyDeleteNow I'm going to feel COMPELLED.
"So today I'm going to subscribe for C."
ReplyDeleteDoes this mean setting up an account with them and entering all of their information?
Is there a way just to have them email you the daily question without telling them your life story?
I think you have to tell them your life story.
ReplyDeleteThat's what I did, as I recall.
Today's question is:

It's coming back to me now...
