According to the website, I have a 0.00604991 chance of winning. That is 100 times more AND it's a different number, which I don't understand how they got there.
Your chance is 0.006% not 0.006.
I have 436 tickets on a total of 2,782,350. That gives me a 0.0001567% chance of winning, while the website says it's 0.01567%. In this case, there is only one winner, so no extra calculations to be done....
That's correct too.
436/2,782,350 = 0.0001567 = 0.01567%
The 0.0001567 must be multiplied by 100 to get the percentage.
