What are the odds of something that statistically should happen 1 in 207 times happening 3 times in 66 occurrences? Let me know.

$$p=\binom{66}{3}(\frac{1}{207})^{3}(\frac{206}{207})^{63}\approx\frac{1}{263}$$
The probability for a single, specific arrangement is $$(\frac{1}{207})^{3}(\frac{206}{207})^{63}$$
