When buying a lottery ticket* you can chose your own numbers or take a lucky dip and have the machine give you random numbers.
My question; Is there a difference in the probability of the two methods? i.e. is there more chance of a win by selecting numbers or using random ones?
I have read up on probability but I don't quite get it enough to work this out myself.
*I only buy a ticket once in a blue moon - it's a cheap way to have a nice daydream !
