Thanks. I did not account for that factor of three.

Actually i did have time to work it out, the exact probability is 2012352988521348/53579221976383488, which is about 3.7558%.

I didn't have time to work out the theoretical probability, but I ran 10,000,000 simulations and it happened 3.74944% of the time. If you want to work it out exact for three lines of 5/36, first calculate the number of ways of obtaining each possible sum from 15 to 170. If N(s) is the number of ways to get a particular sum s then you calculate

3*N(s)*N(s)*[376992-N(s)] where s ranges from 15 to 170. Then divide that total by 376992^3.

The reason why there is a factor of 3 in the formula... [ More ]

Florida Fantasy 5 is a 36-ball game. Last week I bought 2 qps and today after confirming they were losers, I noticed the lines had the same sum. I know how to work out the odds of that happening when I buy just 2 lines.

I'm curious about the odds of it happening if I had bought 3 lines. Meaning, what are the odds of 2 out of 3 having the same sum
