a) What is the probability that a student selected at random in the university is male and majors in math?

b) What is the probability that a randomly selected student in the university is female or majors in math or both?

Based upon the information you provided, out of every 100 students you have this breakdown:

male, math major: 18

female, math major: 12

male, non-math major: 52

female, non-math major: 18

therefore:

a) 18%

b) female: 30%

math major (either !@#$%^&): 30%

female math major: 12%

so for b), you just add them up to get 72%?
