Answer:
Here is code in python.
#define three variables to store grades
grade_1 = 0
grade_2 = 0
grade_3 = 0
//define variable to store average of all three quiz
avg_grade=0
// read score of 1st quiz as integer
grade_1 = int (input ("please enter score of first quiz: "))
// read score of 2nd quiz as integer
grade_2 = int (input ("please enter score of second quiz: "))
// read score of 3rd quiz as integer
grade_3 = int (input ("please enter score of third quiz: "))
//calculate average of three grades
avg_grade = (grade_1 + grade_2 + grade_3)/3
// print the average
print ("Average of three quizs is {}".format(avg_grade))
Explanation:
Declare three variables "grade_1","grade_2" and "grade_3" to store the score of 3 quiz. And variable "avg_grade" to store the average of all quiz.Read score of quiz as integer and then calculate their average and assign it "avg_grade".
Output:
please enter score of first quiz: 23
please enter score of second quiz: 33
please enter score of third quiz: 45
Average of three quiz is 33.6666
