Hey!
I would love to help you with this problem, but there are a few things that need to be clarified.
Is this problem odds in favor of (odd for) or odds against? Also, you stated the odds with a "/" which really makes it a fraction which would imply a probability. To be very clear, you should use a colon 140:289 to state an odd or the word "to." Please clarify.

With odds, you have
s:f (for "odds in favor of")
or
f:s (for "odds against")
Probability is s / (s+f)
So if this is "odds in favor of" the probability is 140 / (289+140) or 140/329
If it's "odds against" the probability is 289/329.
That help?

p = 140/(140+289) = 0.3263

This isn't the ways odds are usually presented, so I can't help you.
