@aum ... can i ask u a question?

aum · Answer

yes?

driftracer305 · Answer

so he got 0.15  by 12/80.........  but y cant we do 62/80 for the probability that is not green?

aum · Answer

because 80 - 12 = 68  (not 62)

driftracer305 · Answer

ahh sorry my bad..... i meant 68.... sorry....

aum · Answer

68/80 = 17/20 = 0.85

driftracer305 · Answer

so we can do that as well right?  68 /80  instead of 12/80  then subtract it from 1?

aum · Answer

Yes.
