This calculator can solve certain probability problems that would take for ever to put into a calculator to solve( if you don't know how to use "!", which I don't) It can solve the birthday paradox and many problems similar it. WARNING Scratch can make rounding errors that can make it slightly off Ex. if you input 113+ people for the birthday paradox scratch will just round it up to 100 rather than 99.9999999...
This project probably won't be relevant to you, but I thought it was cool sooooo why not? :) This started out when a friend didn't do his homework and wanted to know what the chances of him being called were. There were 10 separate opportunities to be called and an original # of 30 people decreasing by 1 whenever someone is called.
