Question

The odds in favor of Carl beating his friend in a round of golf are 9 : 4. Find the probability that Carl will lose.

Answer 1

loses 4 out of 13 right?

Answer 2

\[\frac{4}{13}\] in other words

Answer 3

how did you get that? its correct.

Answer 4

imagine
odds are like this
if you say the odds are say 4 to 17, then 4 times you get it, 17 you don't
so in terms of probability that is like saying if you do it 21 times you get it 4 times and don't 17

Answer 5

or if you like, if the odds are \(m:n\) in favor, then the probability in favor is
\[\frac{m}{m+n}\]

Answer 6

oh! okay cool
