You are wrong. The scenarios are completely different. If you buy 1,000 lottery 
tickets (all with different numbers) then you are 1,000 times more probable to 
win that with one. Still a pretty small chance. 

Pedant for Andy. You have to say "If you toss a KNOWN FAIR coin 50 times and it 
lands on heads every time, it is no more likely to land on tails the next time 
- it will still be the same odds." If I watched someone flip a coin 50 times 
coming heads every time then the odds are that it is a double headed coin.

Is this also true for winning the lottery? That is if you play 1 ticket or 1000 
tickets the odds of winning do not change? I tried to convince someone of this 
but they weren't having it. Am I wrong?

Pedant head on - incorrect, Timbo! If you toss a coin 50 times and it lands on 
heads every time, it is no more likely to land on tails the next time - it will 
still be the same odds. 

Gaffer :P
