My local casino runs a special prize for making a Royal Flush (RF) hand in Hold Em poker. The hand does not have to go to showdown, but both your hole cards must play (i.e. they must be 2 of the 5 RF cards). I was discussing the odds of making such a hand with other players and I got a lot of different feedback, none of which I felt was correct. Here is the scenario:
You have 2 of the 5 RF cards in the hole. Doesn't matter if they are As-Ks or Js-Ts, etc. What are the odds you will get a Royal Flush by street:
a) make RF by the Flop
b) make RF by the Turn
c) make RF by the River
My calculations were as follows:
a1) 19,599 to 1 on the flop
b1) about 5,000 to 1 on the turn
c1) about 2,000 to 1 on the river
The general consensus was the true value by the river was either 60,000 to 1 or 30,000 to 1 by the river. This seems totally nonsensical to me but I was in the distinct minority (i.e. it was only me!). Can someone with more probability know-how step up and provide a definite answer to this question?
Thank You.

I think I agree with your flop math: (3/50)*(2/49)*(1/48)=1 in 19600.

If you have 2 royal flush cards as hole cards the odds that you will make a royal flush by the river using those hole cards are combin(47,2)/combin(50,2) or 1081/2118760 or 1 in 1960. 1/10 the time you flop it. 3/10 it will be made on the turn and 6/10 on the river.

Because in terms of it just generally happening they were correct. It's only about one in 2000 to happen by the river AFTER you get Royal holecards dealt to you, unfortunately 97% of starting hands aren't two Royal cards.
The probability of getting 2 Royal cards to start: 4*C(5,2)/C(52,2) = 40/1326 = 0.030166
