Question 588640: the odds are 3:5 that it will snow tomorrow. what is the probability that it will not snow tomorrow?

Odds in favor = successes:failures


Odds against = failures:successes

Probability of success = successes%2F%28successes%2Bfailures%29

Probability of failure = failures%2F%28successes%2Bfailures%29

You have the odds in favor of snow tomorrow as 3:5.

So "it will snow tomorrow" is considered a SUCCESS and 
"it will NOT snow tomorrow" is considered a FAILURE.

Therefore successes = 3 and failures = 5

The probability that it will NOT snow tomorrow is the probability of a failure:

Probability of failure = failures%2F%28successes%2Bfailures%29 = 5%2F%283%2B5%29 = 5%2F8
