If I've played the lottery a certain $N$ number of times (and I didn't look into the results of each game), what this $N$ number must be to get me a $50\%$ chance of have already won at least one of my games? (imagine I 'll look up at all the results at once, after acheiving this chance) and the chance of winning this particularly lottery is $1$ in $1$ million.
I was discussing this with my colleague and I particularly think that there's no exactly number $N$ of getting $50\%$ of chance of already have won. I think that when you ve played zero games the chance is $0\%$ and if you play an infinite numbers of games the chance is $100\%$ that you have won, but there s no ascending curve.
