You read in a book on poker that the probability of being dealt three of a kind in a fivecard poker
hand is 1/50. What does this mean?
(a) If you deal thousands of poker hands, the fraction of them that contain three of a kind will be
very close to 1/50.
(b) If you deal 50 poker hands, then one of them will contain three of a kind.
(c) If you deal 10,000 poker hands, then 200 of them will contain three of a kind.
(d) A probability of 0.02 is somebody’s best guess for a probability of being dealt three of a kind.
(e) It doesn’t mean anything, because 1/50 is just a number.
