a math class has 50 students , of these 22 students are math majors and 18 students are male. Of the math majors 16 are female. Find the probability that a randomly selected student is male or a math major
P(male or math major) = P(male) + P(math major) - P(male and math major)
P(male or math major) = 18/50 + 22/50 - 16/50
P(male or math major) = 24/50
P(male or math major) = 0.48
