the selected person will be a male is 0.44, and the probability that the selected person
will be a male who was born before 1960 is 0.28.

Best Answer
The answer is given "[...] and the probability that the selected person will be a male who was born before 1960 is 0.28.". So, there are $25*0.28 = 7$ males born before $1960$, so $11-7=4$ is the answer you're looking for.
