Best ResponseYou've already chosen the best response.01/25 is the chance she will draw a wrong address, if she draws 4 times, that would be 1/25 times 4, that would equal 4/100

Best ResponseYou've already chosen the best response.0So if I am right, it would be 4/100 and that can be simplified to 1/25
