Odds To Probability Formula
Given here are the log odds and odds formulas to find the odds, log odds and expected proportion based on the values of any two. The expected proportion is the probability of success on each trial. The odds, also known as 'Odds for' reflect the likelihood that the event will take place, while the 'odds against' is the likelihood that the event will not take place. The log odds is the log of the odds ratio. The odds ratio is a measure of association between an event and the result.
Finding Odds using Probability Probabilities for and against the event can be used as the antecedent and consequent of the ratio representing the odds for an event in place of favorable and unfavorable choices.

Formula:
When Observed Proportion is Giveno = p / (1 - p)
l = log (p / (1 - p))
When Odds is Given
p = o / (1 + o)
l = log(o)
When Log Odds is Given
o = Exp (l)
p = o / (1 - o)
Where,
o = Odds
l = Log Odds
p = Observed Proportion

Odds are used to describe the chance of an event occurring. The odds are the ratios that compare the number of ways the event can occur with the number of ways the event cannot occurr.
The odds in favor - the ratio of the number of ways that an outcome can occur compared to how many ways it cannot occur.
Odds in favor = Number of successes: Number of failures
The odds against - the ratio of the number of ways that an outcome cannot occur compared to in how many ways it can occur.
Odds against = Number of failures: Number of successes
Example
A jewelry box contains 5 white pearl, 2 gold rings and 6 silver rings. What are the odds of drawing a white pearl from the jewelry box?
Number of successes = 5
Number of failures = 2 + 6 = 8
Numbers of ways to draw a white pearl: number of ways to draw another jewelry.
