From the table, total people with 4 Years (or More) of college: $41$

Step2: Identify non-college grads

Total population minus college grads: $172 - 41 = 131$

Step3: Calculate odds in favor

Odds in favor = (Number of successes) : (Number of failures)
$41:131$

Odds against = (Number of failures) : (Number of successes)
$131:41$
