A straight flush in poker is a hand where all five cards are of sequential rank and of the same suit. There are 10 possible sequences (A-5, 2-6, ..., 9-K, 10-A) in each of the 4 suits, making 40 possible straight flushes. Since there are a total of 2,598,960 possible 5-card hands from a 52-card deck (calculated by 52 choose 5), the probability of getting a straight flush is 40 / 2,598,960 = 0.00001539, which rounds to 0.0000154 or 0.0000139 due to approximation or rounding differences in the calculation or presentation.
