Find the probability whose odds against are given in the problem.
Odds against are 1 to 3.
Odds for = 1 - 1/3 = ?
To find the probability whose odds against are given in the problem, we first need to understand what "odds against" means.
Odds against represent the likelihood of an event not happening compared to the likelihood of it happening. In this case, the odds against are given as 1 to 3.
To calculate the probability from odds against, you can use the formula:
Probability = Number of unfavorable outcomes / Total number of outcomes
In this case, the odds against are given as 1 to 3. This means that for every 1 favorable outcome, there are 3 unfavorable outcomes.
So, the number of unfavorable outcomes is 3 and the total number of outcomes is 1 (favorable) + 3 (unfavorable) = 4.
Now, substitute these values into the formula:
Probability = 3 / 4
Therefore, the probability whose odds against are given as 1 to 3 is 3/4, which can also be written as 0.75 or 75%.
