Answer #1

Total number of students(Overall students) = 72

Total Male student = 38, Total female student = 34

Student with grade A = 21, Student with grade B = 24 and student with grade C = 27

P(Student was male Or got an A)

The formula to find the OR probability is,

P(Student was male OR got A) P(Male)+P(Grade A)-P (Student was male And got A)

Total male students Qverall students 38 P(Male)

Total students with grade A Qverall students 21 P(Grade A)-

Number of students who are male as well as they got A Qverall students P(Student was male And got grade A)

18 P(Student was male And got grade A)

Plug all these values in the formula of required probability,

P(Student was male OR got A) P(Male)+P(Grade A)-P (Student was male And got A)

P(Student was male OR got A) 38 21 18 38 21 - 18 41 72 18 72 72 72

P(Student was male OR got A)0.57 Rounded to two places.

Therefore, the probability that the student was male or got an A is 0.57
