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?

Your friend is mistaken. The odds of winning Euromillions are close to 1 in 140,000,000. The 1 is for the 1 set of numbers you get on each ticket. When you buy two tickets, you have 2 sets of numbers that could match the winning the numbers. So, your odds are 2 in 140,000,000.
So long as each ticket has a different set of numbers, you can double your odds simply by doubling the number of tickets you buy.
