From a full 52-card deck of playing cards some cards were removed.
Now we shuffle and draw 2 cards and find them both red.
1. The probability of both cards being red was 50%.
2. There was an equal number of cards in each of the following suits: CLUBS, DIAMONDS & SPADES.
How many hearts were initially in the partial deck?
(In reply to Solution
(3,3,12,3) is a correct answer for set (C,D,H,S).
Probability of red ...2nd draw = (x+h-1)/(3x+h)
(Probability of red ...2nd draw = (x+h-1)/(3x+h-1).
BTW -you still did not comment on my last remark re "penta-quadratic"
