What we measured
Flopping a royal flush means holding a five-card royal flush (10-J-Q-K-A of one suit) right on the flop. That requires being dealt two of those five cards suited and flopping the other three — the whole royal is complete before the turn. The table figures show the chance any player flops a royal.
How it was calculated
Exact combinatorics: 40 qualifying two-card holdings out of C(52,2), each needing one exact 3-card flop out of C(50,3). Player events are mutually exclusive, so the table figures are exactly additive.
