CHECKING NOT SO CAREFUL


Attention to detail is a crucial part of the job:
I’m a lawyer. I check these things regularly...
Let’s see just how closely everyone's favourite lawyer checks things. In this post, Jeremy quotes David Starkoff:
Winning division 1 in Oz 7 Lotto requires picking the seven winning numbers from 45: 45,379,620 combinations. Since you can buy a 12-game ticket for $12.70, the entry cost to buy every combination is therefore a shade over $48,000,000… This suggests that a brute force attack may be efficient: i.e., buying every combination and making a profit.
The important words in that extract, which Jeremy presumably checked carefully: “12-game ticket.” But Jeremy goes on to write:
I think he’s got the maths wrong by a factor of about ten. $12.70 multiplied by 45,379,620 is $576,321,174, not $48 million. Unless I’m missing something.
He has. He’s missed the fact that a 12-game ticket (there’s a clue in the name) plays 12 games, not just one. Alerted to this by a reader, Jeremy responds:
Ah – I didn’t know that.
Almost 24 hours later Jeremy finally corrected his post. Such admissions are rare indeed and should be savoured.

Update: Jeremy can't fact check a paragraph he quotes but takes journalists to task for not getting it right. Tee hee.

Read JS's post in the context of his latest ramble at PP on fact checking for extra LOLs.
