A bag contains 9 green marbles and 11 white marbles. You select a marble at random. What are the odds in favor of picking a green marble?
A. 9:20
B. 2:9
C. 11:9
D. 9:11
(I think its a.)
She is right its is 9:20 because you have to add 9+11=20
Then it would be 9 to the total
9:20
i farted in the pool
so is Mrs. sue right
jeez don't degrade Ms.sue if you cant even do the work besides, how did you get 1/2 out of 9/20 in the first place?!
odds and probability are not quite the same
odds in favour of some event
= prob of that event : prob of NOT that event
so ...
prob of picking a green = 9/20
prob of not picking green = 11/20
odds in favour of picking a green
= 9/20 : 11/20
= 9 : 11
which is D
yes Ms.Sue is correct (on the test it was right)
