Odds are desired outcomes : undesired outcomes.
In this case, %281%2F2%29%3A%281%2F2%29 or 1%3A1

Hi

Let's consider: p = 4/7, 

this tell us there are 4 successes out of 7 trials (AND 3 failures out of 7 trials)

ODDs in favor (of success) are 4:3

p = 1/2, 

this tell us there are 1 success out of 2 trials (AND 1 failure out of 2 trials)

ODDs in favor(of success) are 1:1
