Question : A) if a student is chosen at random , what is the probability that the student recieced grade-D? B) if C or above is considered as a pass grade , and if a student was chosen at random, what is the probability that the student received a pass grade ? C) what is the probability that the student selected at random for a fail grade ?
Explanation / Answer
A) if a student is chosen at random , the probability that the student recieced grade-D = Number of students with 'D' grade/Total number of students
Number of students with 'D' grade = 0
Total number of students = 11
if a student is chosen at random , the probability that the student recieced grade-D = 0/11 = 0
B)if C or above is considered as a pass grade , and if a student was chosen at random,
probability that the student received a pass grade = Number of Students received a pass grade / Total number of students
Number of Students received a pass grade = Number of students C or above C grade = Number of Students with C grade + Number of students with B Grade + Number of students with A Grade = 1+1+7 = 9
probability that the student received a pass grade = Number of Students received a pass grade / Total number of students = 9/11
probability that the student received a pass grade = 9/11
C)
Student either receive a pass grade or a fail grade
probability that the student selected at random for a fail grade = 1 - probability that the student selected at random received a pass grade = 1- 9/11 = 2/11
