A spokesman for the Jackson family revealed that after only seven hours, over 500,000 people had entered the lottery for memorial tickets. Okay, time for some quick math: that means that roughly 71,500 people per hour have signed up. And if you extend that rate for the remaining 25 hours (especially since the lottery has been opened up to the entire world), you get a total number of around 2.3 million.
Only 8,750 of those people will get tickets to the memorial (two tickets per person), and some of those people will get only get passes to the "satellite event" in the Nokia Theatre across the street-- like watching it on TV but in a pressure cooker with thousands of other people.
The bottom line: a 0.4% chance of getting a ticket. The good news? You're still more likely to get a ticket than get struck by lightning.
