Steps/Work
Science majors make up 0.4 of the class.
60% of the class are women and 0.2*0.6 = 0.12 of the class are female science majors.
Then 0.28 of the class are male science majors.
0.4x = 0.28
x = 0.7 = 70%
The answer is D.
60% of the class are women and 0.2*0.6 = 0.12 of the class are female science majors.
Then 0.28 of the class are male science majors.
0.4x = 0.28
x = 0.7 = 70%
The answer is D.
