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?

People don’t believe it is the issue.
Let’s say to start the odds are 1 in ten
If you have a 1 in 10 chance of winning something for each ticket you buy and you buy two tickets you have a 2 in 10 chance to win.
That’s the same as 1 in 5.
Up those odds to 1 in 140,000,000 and when you buy two tickets your odds are 2 in 140,000,000 or 1 in 70,000,000
I have tried to explain this to several people and the end result is they don’t understand it for some reason and don’t believe that buying 2 tickets increases your odds of winning by that much.
It’s very very basic math. However it’s still only 1 in 70,000,000 which is still terrible odds of winning
