Suppose I said to you: Alan, if you buy a powerball ticket with 6 "Quick Picks", how likely is that you have a (red) Powerball number that's a duplicate? You'd probably say, oh the chances must be very small. 26 (red) Powerballs to choose from and I pick only 6.
But in fact, the odds are almost 50/50 that you'll have a repeater (red) Powerball on that ticket.
