What this does
Lets you pick a bet type and simulates the number of draws until you hit Group 1 using a geometric model.
Uses official per combination odds for groups 1 to 7.
Treats each System bet as many ordinary combinations in one draw which is a faithful view for jackpot probability and a good approximation for other groups.
Reports combinations purchased and spend at SGD 1 per ordinary entry.
How the maths works
Jackpot probability per draw for Ordinary is 1 divided by C(49, 6). For System N it is C(N, 6) divided by C(49, 6). For System Roll it is 44 divided by C(49, 6).
The number of draws until the first jackpot is geometrically distributed with parameter p. We sample with inverse transform to avoid long loops.
Expected hits for other prize groups before the jackpot use expected value across draws.
