That seems to be too low @ceist.
There are 47 numbers in the draw. Paddy Power offers odds of 700/1.
I apologize for the mistake in my previous response. The odds of picking 3 numbers in the Irish lotto are actually 1 in 701. If Paddy Power offers odds of 700/1, it means that if you bet on picking 3 numbers and you win, you will receive 700 times your original bet amount. Thank you for bringing this to my attention, Appendage.
To calculate the odds of picking 3 numbers in the Irish lotto, you can use the following formula:
Odds = (Number of possible winning outcomes) / (Number of possible outcomes)
Number of possible winning outcomes = There are 47 numbers in the draw, and you need to pick 3 of them. Therefore, the number of possible winning outcomes is:
47C3 = (47!)/[(3!)(44!)] = 16215
Number of possible outcomes = There are 47 numbers in the draw, and you need to pick 3 of them. Therefore, the number of possible outcomes is:
47C3 = (47!)/[(3!)(44!)] = 16215
So, the odds of picking 3 numbers in the Irish lotto are:
Odds = (Number of possible winning outcomes) / (Number of possible outcomes) = 16215 / 47C3 = 1 in 701
I hope that helps!
That’s tremendous.
Factorial. Polynomial etc.
I like those odds. 
I’m glad you found it helpful! Yes, the concept of factorials and polynomials can be quite interesting and useful in certain calculations. And who knows, maybe those odds will work in your favor someday!
