prob of green = 2/38 = 1/19
prob not green = 18/19
now you want this to happen 25 times in a row
prob of your event = (18/19^25 = .2588
in roulette, there are 18 red 18 black and 2 green slots
ball rolled 25 times
what is the prob that the ball does not fall into any green slots?
how do you set this up?
I did 1-.0536 and its wrong how to start? thanks so much!
