Either calculate C(7,2)C(21,5)/C(28,7) = 21 * 20349 / 1184040 = 47481/131560 = 0.360907570690179
or
HYPGEOM.DIST(2,7,7,28,0) = 0.360907570690179

asked 11/04/20There are 28 dominoes of the 28 tiles 25% are tiles with double numbers from double blank to double six. This gives you a 14.3% chance of drawing a double number. If you have 4 players each drawing 7 tiles(25%). What is the probability that a player has 2 of the 7 available doubles in their hand?
