A Royal Flush
To put this in perspective, for poker players the probability of getting a royal flush in poker is at 1 in 649,740, and the probability of an amateur hitting a hole-in-one in golf is hundreds of times as great, at 1 in 12,000.
Not four of a kind, but three this time. Three family members deciding to step away from the British Crown today and be part-time Royals. The UK is not OK -Liz is pissed.
