I mentioned to a colleague that I’d bought two lottery tickets for last weeks Euromillions draw instead of my usual 1 to double my chance at winning. He said “Yeah, that’s not how it works.” I’m sure he is right – but why?

There are almost 14million combinations for the lottery so the odds of the jackpot for 1 and 2 tickets is;
1/14000000
2/14000000 = 1/7000000
The odds are halved with a second ticket so you were right originally
