Title: calling a card's color
Post by Jacob on Feb 23^rd, 2003, 8:37pm

i'm not sure if i understod this right but here's my way...
when you draw a red card count it as plus one and when you draw a black card count it as minus one. when the sum of the cards you have drawn are positive it means that more red cards have been drawn and there should be more black cards left in the deck, and it works the other way around a negative sum means that more black cards have been drawn and there should be more red cards in the deck.
so all you have to do is draw 51 cards, if you then have counted to +1 the next card is black and if you have -1 the next card is red

There is already a thread for this puzzle here (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_medium;action=display;num=1039561777).

The guesser is not allowed to guess either color. His task is to predict the turning over of a red card only.
