Write a Python program that asks the user for quantity and takes some marks out of 100 as input. Valid marks are 0 to 100. However, due to user error, some marks may fall outside that range, say 101 or -5 (minus five). Print average of valid marks and percentage of invalid marks (Error Rate). Assume there is at least one valid mark and at least one invalid mark.

Transcribed Image Text:Sample Input 2:
3
500
100
Sample Output 2:
Average: 51.5
Error Rate (%): 33.33333333333333
Explanation 2:
3 means there are 3 inputs.
Average of valid marks is (3+100)/2 = 103/2 = 51.5
500 is invalid. So, there is 1 number out of 3 that is invalid. Hence the percentage = 1/3x100
= 33.33333333333333

Write a Python program that asks the user for quantity and takes some marks out of 100 as
input. Valid marks are 0 to 100. However, due to user error, some marks may fall outside
that range, say 101 or -5 (minus five). Print average of valid marks and percentage of invalid
marks (Error Rate). Assume there is at least one valid mark and at least one invalid mark.
Sample Input 1:
5
20
-3
105
70
100
Sample Output 1:
Average: 63.333333333333336
Error Rate (%): 40.0
Explanation 1:
5 means there are 5 inputs.
Average of valid marks is (20+70+100)/3 =190/3 = 63.333333333333336
-3 and 105 are invalid. So, there are 2 numbers out of 5 that are invalid. Hence the
percentage = 2/5x100 = 40.0
