Sagot :
Answer:
To find the probabilities, you need to calculate the frequency of each score and then divide by the total number of scores, which is 16 in this case.
Step-by-step explanation:
a) Probability of scoring 3 marks:
There are 2 students who scored 3 marks.
Probability = (Number of students scoring 3 marks) / (Total number of students)
Probability = 2/16 = 1/8
b) Probability of scoring 4 marks:
There are 4 students who scored 4 marks.
Probability = (Number of students scoring 4 marks) / (Total number of students)
Probability = 4/16 = 1/4
c) Probability of scoring odd marks:
Odd marks are 3, 5, 7, 9.
There are 2+1+1+1 = 5 students who scored odd marks.
Probability = (Number of students scoring odd marks) / (Total number of students)
Probability = 5/16
d) Probability of scoring even marks:
Even marks are 2, 4, 6, 8, 10.
There are 2+4+2+1+2 = 11 students who scored even marks.
Probability = (Number of students scoring even marks) / (Total number of students)
Probability = 11/16
e) Probability of scoring a mark less than 5:
Marks less than 5 are 2, 3, and 4.
There are 2+2+4 = 8 students who scored less than 5 marks.
Probability = (Number of students scoring less than 5 marks) / (Total number of students)
Probability = 8/16 = 1/2
