Given that he is male means you have to choose from the male column

Total in the male column is 4709
does not have a Master's degree.

I would assume the other 3 degrees would be okay.... 2023+2225+45

4293/4709 =.9116

or you could find 416/4709 = .08834
which means has a master's degree, but you would have to subtract that value from 1 to get does not have a master's degree to get .9116
