Actually, according to experts, the logical thing to do is to take the lump sum and invest it properly. We would invest most of it, after paying off bills, giving money to family and setting up a charitable organization, and live off the interest for a while. You will make more in the long run than you would ever get from the annuity offered through the lottery. We would never take the offered annuity.
Also, only means their chances are 72,500 out of 200+ million, (1 out of 200+ million per ticket). So, it only increases their chances by a very small amount (miniscule) as each ticket still only has a 1 in 200+ million chance. Each ticket would have to have completely different numbers also in order to increase the odds.
I "won" $4 last night. A week ago I won $8 (matched powerball twice) on $20 worth of tickets. I turned around and reinvested in 4 more tickets on which I won zero. DH bought 5 more tickets on Monday and on that I matched the powerball on one line so $4. So, out of $30 spent, I got $12 back. Pretty good deal for the state.
