The name of your class is "Check Work"? That's unusual!
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
