Andrei has a bag of x sweets.
He removes two sweets from the bag simultaneously (without replacement).
He now removes a third sweet.
The probability that the third sweet is red is (x/2) - 1.
How many red sweets were in Andrei's bag to begin with?
Could somebody please tell me if (and how) it is possible to solve this problem?
Thank you very much for your help in advance!
