Does a flush beat three of a kind?
Yes. A flush beats three of a kind in poker — every time. In the ranking of 10 hand categories, flush is #5 and three of a kind is #7. Categories are compared first: even a seven-high flush beats three aces — the category always decides first.
Five cards of one suit, any order.
Three cards of the same rank ("trips").
How rare is each hand?
Rarity is exactly why the order is what it is. Out of 2,598,960 possible five-card hands, a flush shows up in 0.197% of them (5,108 combinations), while three of a kind appears in 2.11% (54,912 combinations). The harder a hand is to make, the higher it ranks.
Does three of a kind ever beat a flush?
No — never. The category comparison is absolute: the highest possible three of a kind still loses to the lowest possible flush. Ranks inside a category only matter when both players hold the same category.
