Explanation / Answer
Probability that randomly selected student is male , given that student is nursing major
= Number of male students under nursing major / Number of students under nursing major
= 98 / 830 =0.118
Probability that randomly selected student is male , given that student is nursing major = 0.118
Probability that randomly selected student is nursing , given that student is male
= Number of students under nursing major who is male / Number of male students
= 98/1245 = 0.079
Probability that randomly selected student is nursing , given that student is male = 0.079
