My husband is in the National Guards and a while back I had this nightmare that his unit had been deployed to Iraq and he was killed while over there. Very next day he finds out his unit was scheduled to be deployed. They left home a few days ago and are doing some training in states for a month or so before heading over. Is it more likely that the rest of my dream would come true? If so is there any way to stop it from happening?

I need to know the best way of determining the lottery game I should spend my $1 on. In Illinois, I can basically choose between the Illinois Lottery and the Mega Millions game for the large jackpots. The Mega Millions has a larger jackpot, but the probability of winning is smaller. The Illinois Lottery has a smaller jackpot but a better probability of winning. Because the jackpots of these two lotteries fluctuate, I want to know the best way of determining the better lottery “value”. I was thinking that I should multiply the probability of winning the jackpot times the jackpot (in dollars) for each lottery. The lottery with higher number should be the better value. Is this correct, or is there another way of determining the better choice?
