Calculate the probability of the event not occurring given odds in favor of

7:5

Odds Against Formula is denoted below:

P(failure)  =  n
  m + n

Plugging in the values you entered of m = 7 and n = 5, we have:

P(failure)  =  5
  7 + 5

P(failure)  =  5
  12

Final Answer


P(failure) = 0.41666666666667
