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?

If you try to guess which number i am thinking of in a 1..10 range and say 1 number it’s a 1/10 chance. If you say 2 different numbers it’s a 2/10 chance which has a better chance to be correct ( in this case, twice as likely)
