Please read the following excerpt from a wonderful book "The jungle of randomness" (by Ivars Peterson) and supply the missing numbers - to the best of your judgement.

You may make your own assumptions, define the population, time etc …

40,000,000 buy 4 tickets per month
40,000,000 buy 40 tickets per month.
results in 1,800,000,000 tickets per month.
Assuming a $1 ticket (which is what I think you are implying when you give one chance in 10,000,000), this is $450,000,000 per week. Since any given lottery takes in $10,000,000, this implies 45 $1 million lotteries per week in the US.
Is that what you are in fact assuming? Did I make a mistake? Did you?
By the way, I looked it up, and Americans spend $70 billion per year, a little over 1.3 billion a week, on lottery tickets. But most of this amount are on megabucks and powerball, which have much bigger jackpots than $1,000,000.
