Google Calculator cheat sheetPosted: September 26, 2008 | Author: tech0x20 | Filed under: math | Leave a comment »
My first find was the Quick Reference: Google Calculator (Cheat Sheet).
I like this tip from Google Guide solutions to Calculator problems:
Compute the probability of your winning the lottery if you buy 1,000 tickets each bearing five distinct independently randomly chosen integers between 1 and 99.
The following answer was contributed by Nelson Blachman (Nancy’s father).
You might try [ 1 – (1 – 1/(99 choose 5))^1000 ], but this is well approximated by [ 1000/(99 choose 5) ], which is roughly 0.00001 . If each ticket costs $1, the prize had better be at least $100 million to be fair to you — and higher if you might have to share the prize with other winners.
Also… I've always wanted to figure out the probability calculation for various poker hands.
