[Field Marshal Dr. Opti]

My lad has Aspergers, he is a wizard at maths and puzzles. He loves 'Only connect' whereas I just stare blankly at it. He was explaining to me about a question he got right and complaining it was getting easier. If you haven't seen it, you get a series of four statements/numbers/letters etc, and the earlier you get the fourth one, the more points you get. Here's the question:

1) A(1in 13)    2) AA(1in17)     Then he got it. What?
If you have seen it, please don't jump in.

Right, for those that are interested..it's the probability of choosing any ace from a pack of cards.

1) There are four aces and 52 cards so 4/52=13.
2) There are now three aces and 51 cards so 3/51=17
3) There are now 2 aces and 50 cards so 2/50=25
The answer they were looking for 4) AAAA (1 in 49)

Yep.....easy when you know how........only I didn't.

Don't fret..I had batteries in mind.

You should have been charged years ago.....

Seems the challenge in this particular example is actually correlating the letter A with Ace, (which not being a Card-ist I didn't), rather than mathematical skill.  Once you've got that far it's obvious...

Exactly...that's the point.
